The probability of all four selecting a seat being 1/2016, or 0.05%, which is equivalent to 6/10, or 60%.

n a lecture hall, the probability of four students randomly sitting in a row of 10 seats with at least one seat between them is relatively high. This is because the four students have a total of 6 empty seats to choose from. This means that the probability of them all sitting at least one seat apart from each other is 6/10, or 60%.

To further explain, the probability of each student randomly selecting a seat from the 10 available is 1/10. However, as the students are sitting in a row, there are certain conditions to be taken into account. For example, the first student must select a seat from the first 9 available, as the last seat is already taken by the fourth student. The second student must select a seat from the remaining 8 available, and so on. This means the probability of each student selecting a seat is 1/9, 1/8, 1/7 and 1/6, respectively.

When the probability of all four students selecting a seat is combined, we can calculate the probability of them all sitting at least one seat apart from each other. This is calculated as

1/9 x 1/8 x 1/7 x 1/6 = 1/2016.

This means that the probability of the four students all sitting at least one seat apart from each other is 1/2016, or 0.05%, which is equivalent to 6/10, or 60%.

There are 9000 4-digit numbers from 1000 to 9999. There are 10,000 5-digit numbers that end in I. There are 1,000 5-digit numbers that end in 0. There are 10,000 5-digit numbers that are multiples of 10.

(a) To determine the number of 4-digit numbers from 1000 to 9999, we subtract the starting point (1000) from the ending point (9999) and add 1 since we're including both endpoints. Therefore, the number of 4-digit numbers is:

9999 - 1000 + 1 = 9000.

(b) To count the number of 5-digit numbers that end in I, we need to determine the possible values for the other four digits. For each of the other four digits, there are 10 possible choices (0-9). Therefore, the number of 5-digit numbers ending in I is:

10^4 = 10,000.

(c) To count the number of 5-digit numbers ending in 0, we again need to determine the possible values for the other four digits. For each of the other four digits, there are 10 possible choices (0-9). However, for the last digit, it must be 0. Therefore, the number of 5-digit numbers ending in 0 is:

10^3 = 1,000.

(d) To count the number of 5-digit numbers that are multiples of 10, we need to determine the possible values for the other four digits. For each of the other four digits, there are 10 possible choices (0-9). Again, the last digit must be 0 since it is a multiple of 10. Therefore, the number of 5-digit numbers that are multiples of 10 is:

10^4 = 10,000.

It must change systematically when the independent variable is changed for an extraneous variable to become a confounding variable that is option D.

This is because a confounding variable is a variable that is related to both the independent and dependent variables and affects the outcome of the study, making it difficult to determine the true effect of the independent variable. In order for a variable to be considered a confounding variable, it must change systematically with changes in the independent variable.

A confounding variable is a variable that affects the outcome of a study but is not the variable of interest. This can create ambiguity in the results and make it difficult to determine if the observed effect is due to the independent variable or the confounding variable. In order for a variable to be considered a confounding variable, it must change systematically with changes in the independent variable.

This means that as the independent variable changes, the confounding variable also changes in a predictable way. Without controlling for this variable, the study may not accurately reflect the true effect of the independent variable. Therefore, it is important to identify and control for confounding variables in a study to ensure that the results are valid and reliable.

Step-by-step explanation:

The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.

The population proportion who participated in voting is given as 63% of all registered voters.

This means that out of every 100 registered voters, 63 participated in voting.

In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.

Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .

Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.

It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.

Answer:

He bought 12 $0.25 costing cards and 8 $0.15 costing cards.

Step-by-step explanation:

Let the number of $0.25 costing cards he bought be s,
Let the number of $0.15 costing cards he bought be t,
According to the question,
He bought a total of 20 game cards,
Thus,
s + t = 20
or, s = 20 - t ------(i)
Now,
Since, he bought s and t no of cards each and it amounted to $4.2, we know,
$0.25s + $0.15t =  $4.2
or, $0.25(20 - t) + $0.15t =  $4.2 [From (i)]
or, $5 - $0.25t + $0.15t =  $4.2
or, $5 - $4.2 = $0.1t
or, $0.8/$0.1 = t
t = 8
From (i),
s = 20 - t = 20 - 8 = 12
Therefore, he bought 12 $0.25 costing cards and 8 $0.15 costing cards.

The defect rate for your product has historically been about 1.50% For a sample size of 200, the upper and lower 3​-sigma  The upper control limit (UCL) is approximately 0.0450.

The upper control limit (UCL) for a 3-sigma control chart is given by:

\(\[UCL\) = defect rate + 3 * sqrt((defect rate * (1 - defect rate)) / sample size)

Substituting the values, where the defect rate is 1.50% (0.015) and the sample size is 200, we get:

\(\[UCL = 0.015 + 3 \times \sqrt{\frac{0.015 \times (1 - 0.015)}{200}}\]\)

Calculating this expression, we find:

Findings of an intervention study with a convenience sample should be replicated before being applied to a wider population.

The correct answer is: d.
This is because a convenience sample may not be representative of the entire population, and thus, the findings might not be generalizable to a wider group of patients with related problems.

Replicating the study with a more diverse sample can help ensure the results are applicable to a broader population.

The correct answer is d :

Findings of an intervention study with a convenience sample should be replicated before being applied to a wider population.

Convenience sampling involves selecting participants based on their availability and willingness to participate, rather than randomly selecting them from a larger population.

As a result, convenience samples may not be representative of the larger population and may have biases that affect the generalizability of the findings.

Therefore, it is important to replicate the study using a more representative sample before drawing conclusions that can be applied to a wider population.

This helps to ensure that the findings are reliable and can be generalized to the broader population.

The value of chi-square cannot be negative. Therefore, it is likely that the researcher made a mistake in calculating or reporting the value of the chi-square statistic. Chi-square is a non-negative measure of the discrepancy between observed and expected frequencies.

Chi-square is a non-negative measure of the discrepancy between observed and expected frequencies. It is calculated by comparing the observed frequencies with the expected frequencies under a particular hypothesis. The chi-square statistic can be used to test the goodness of fit of a model, or to test for independence between two categorical variables.

If the value of chi-square is negative, it suggests that the observed frequencies are consistently larger than the expected frequencies, which is not possible. Therefore, it is important to carefully check the calculations and data before drawing any conclusions. It is also possible that there were errors in the data collection or measurement, which could affect the validity of the results. In any case, the negative value of chi-square is a red flag that warrants further investigation and validation of the results.
