Sales Revenue
• Total sales revenue was £120 million in Quarter 1.
• Total sales revenue in Quarter 2 decreased by £10 million compared to Quarter 1.
• Sales revenue in the East was £78 million in Quarter 1.
• Sales revenue in the West Increased by £46 million from Quarter 1 to Quarter 2.
Question
Arrange the sales revenue (in '000,000s) by quarter and the percentages in the East and West
regions.
£160
Answers
Percentage in the East: 65%
Percentage in the West: 80%
Based on the given information, we can arrange the sales revenue and calculate the percentages for the East and West regions as follows:
Quarter 1:
Total sales revenue: £120 million
Sales revenue in the East: £78 million
Sales revenue in the West: Total sales revenue (£120 million) - Sales revenue in the East (£78 million) = £42 million
Quarter 2:
Total sales revenue: Total sales revenue in Quarter 1 (£120 million) - Decrease of £10 million = £110 million
Sales revenue in the East: £78 million (remains the same as Quarter 1)
Sales revenue in the West: Increase of £46 million from Quarter 1 (£42 million) + £46 million = £88 million
To calculate the percentages for the East and West regions:
Percentage in the East: (Sales revenue in the East / Total sales revenue) * 100
= (£78 million / £120 million) * 100
= 65%
Percentage in the West: (Sales revenue in the West / Total sales revenue) * 100
= (£88 million / £110 million) * 100
= 80%
Therefore, the sales revenue by quarter and the percentages in the East and West regions are as follows:
Quarter 1:
Total sales revenue: £120 million
Sales revenue in the East: £78 million
Sales revenue in the West: £42 million
Quarter 2:
Total sales revenue: £110 million
Sales revenue in the East: £78 million
Sales revenue in the West: £88 million

According to a study on the effects of smoking by pregnant women on rates of asthma in their

developed asthma by the age of two in the US. A biology professor at a university would like to
test if the percentage is lower in another country. She randomly selects 341 women who only
deliver one child and smoke 20 cigarettes per day during pregnancy in that country and finds that 71 of the children
developed asthma by the age of two. In this hypothesis test,

Answers
part1)Rounding to four decimal places, the test statistic is z = -1.7918. part2) Rounding to four decimal places, the p-value is p = 0.0728.
what is decimal places ?
Decimal places refer to the number of digits to the right of the decimal point in a decimal number. For example, in the decimal number 3.14159, there are 5 decimal places, with the digit 1 being in the first decimal place, the digit 4 being in the second decimal place, and so on.
In the given question,
Part 1:
To calculate the test statistic, we use the formula:
z = (p - P) / √[(P(1-P))/n]
where p is the sample proportion (71/341 = 0.2082), P is the hypothesized proportion (0.227), n is the sample size (341).
z = (0.2082 - 0.227) / √[(0.227 * 0.773)/341]
z = -1.7918
Rounding to four decimal places, the test statistic is z = -1.7918.
Part 2:
To calculate the p-value, we use a standard normal distribution table or a calculator. Since this is a two-tailed test, we calculate the area in both tails of the distribution.
Using a calculator or a standard normal distribution table, we find that the area to the left of z = -1.7918 is 0.0364. Therefore, the area in the right tail is also 0.0364.
Thus, the p-value is 2*0.0364 = 0.0728.
Rounding to four decimal places, the p-value is p = 0.0728.
Therefore, we would fail to reject the null hypothesis at the 0.05 significance level since the p-value is greater than the level of significance. We do not have enough evidence to suggest that the percentage of children who develop asthma by age two for expectant mothers who smoke 20 cigarettes per day during pregnancy is lower in this other country compared to the US.

200.60 interest does andy’s account earn.
Let x be the amount of interest earned by Andy's account.
According to the problem, Andy's account earns 0.3% more interest than Marty's account, which means that Andy's account earns the same amount plus an additional 0.3% of that amount. Mathematically, we can express this as:
x = 200 + 0.3% of 200
Simplifying the right-hand side of the equation, we get:

The circumference of the given circle is approximately 47.3 inches.
Since the length of the arc KL and the measure of the central angle ∠KOL are known, we can use the formula for arc length to find the circumference of the circle:
arc length = (central angle / 360°) x circumference
Plugging in the known values, we have:
4.6 in = (35° / 360°) x circumference
Solving for the circumference, we get:
circumference = 4.6 in / (35° / 360°)
circumference = 4.6 in x (360° / 35°)
circumference ≈ 47.3 in (rounded to the nearest tenth)
Therefore, the circumference of the circle is approximately 47.3 inches.

.
(Round to three decimal places as needed.)
Part 2
Interpret your results. Choose the correct answer below.
A. With 99% confidence, it can be said that the sample proportion of adults who say they have started paying bills online in the last year is between the endpoints of the given confidence interval.
B. The endpoints of the given confidence interval show that adults pay bills online 99% of the time.
C. With 99% confidence, it can be said that the population proportion of adults who say they have started paying bills online in the last year is between the endpoints of the given confidence interval.
Answers
The correct answer is Part 1: The 99% confidence interval for the population proportion is approximately (0.4716, 0.5416).Part 2: With 99% confidence, the population proportion of adults who say they have started paying bills online in the last year is between the endpoints of the given confidence interval.
Part 1:
To construct a 99% confidence interval for the population proportion, we can use the formula:
Confidence Interval = Sample Proportion ± Margin of Error
where the margin of error is determined by the level of confidence and the standard error.
First, let's calculate the sample proportion:
Sample Proportion = (Number of adults who say they have started paying bills online) / (Total number of adults surveyed)
Sample Proportion = 1436 / 2837 ≈ 0.5066 (rounded to four decimal places)
Next, we need to calculate the standard statistics error, which is the measure of the variability in the sample proportion:
Standard Error = sqrt((Sample Proportion * (1 - Sample Proportion)) / Sample Size)
Standard Error = sqrt((0.5066 * (1 - 0.5066)) / 2837) ≈ 0.0136 (rounded to four decimal places)
Now, we can calculate the margin of error:
Margin of Error = Critical Value * Standard Error
The critical value is based on the desired confidence level. For a 99% confidence level, the critical value is approximately 2.576 (obtained from a standard normal distribution table).
Margin of Error = 2.576 * 0.0136 ≈ 0.0350 (rounded to four decimal places)
Finally, we can construct the confidence interval:
Confidence Interval = Sample Proportion ± Margin of Error
Confidence Interval = 0.5066 ± 0.0350
Confidence Interval ≈ (0.4716, 0.5416) (rounded to four decimal places)
Part 2:
The correct interpretation is:
C. With 99% confidence, it can be said that the population proportion of adults who say they have started paying bills online in the last year is between the endpoints of the given confidence interval.
This means that we are 99% confident that the true proportion of adults who have started paying bills online falls within the range of 0.4716 to 0.5416. The survey results suggest that approximately 47.16% to 54.16% of the population of adults have started paying bills online in the last year.

Answers
Answer:

Step-by-step explanation:
If Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.
What is percentage?A percentage is the number or ratio which is expressed as a fraction of 100.
How to calculate percentage?We have been given the buying value=$8000
Selling value=$7500
Loss=Buying value- selling value
=8000-7500
=$500
Percentage of loss=loss/ buying value*100
=500/8000*100
=6.25%
If we want to check our answer then we can multiply our percentage with the buying value.
=8000*6.25%
=500
Hence if Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.
