Sample variance and standard deviation are considered biased estimates of population variance and standard deviation because they tend to underestimate the true population variance and standard deviation.

The reason for this is that the sample variance and standard deviation are based on a sample of the population, not the entire population. The sample may not accurately represent the entire population, and thus the sample variance and standard deviation may not accurately reflect the true population variance and standard deviation. To correct for this bias, a correction factor is usually added to the sample variance calculation. For example, when estimating the population variance from a sample of size n, the sample variance is divided by (n-1) instead of n. This correction factor helps to provide a more accurate estimate of the population variance. Similarly, the sample standard deviation is calculated as the square root of the sample variance, and the correction factor is also applied to the sample standard deviation calculation. This corrected sample standard deviation is known as the unbiased sample standard deviation.

Mount Everest is 8,813 m high.

Given height of Kula Kangri is 7554 m

Given that,

Kula Kangri ⇒ 7554m

Mount Everest ⇒ \(1\frac{1}{6}\)  the height of Kula Kangri

So, to find the height of Mount Everest you have to multiply the height of Kula Kangri by  \(1\frac{1}{6}\).

Before solving this, we have to make 1 1/6 as an improper fraction.

\(1\frac{1}{6} = > \frac{7}{6}\)

Let us solve it now.

The equation cos(2x) = -√2/2 has two solutions in the interval 0 ≤ x ≤ 2π, which are x = π/8 and x = -π/8.

To solve the equation cos(2x) = -√2/2, we can use the properties of the cosine function and trigonometric identities.

First, let's find the reference angle whose cosine is -√2/2. The reference angle is the acute angle between the terminal side of an angle and the x-axis in the standard position.

We know that cos(π/4) = √2/2, and since the cosine function is an even function, cos(-π/4) = √2/2 as well. Therefore, the reference angle is π/4.

Now, we need to find the values of x between 0 and 2π that satisfy the equation cos(2x) = -√2/2.

Since cos(2x) = cos(π/4), we have two cases to consider:

2x = π/4

2x = -π/4

For case 1, solving for x gives:

2x = π/4

x = π/8

For case 2, solving for x gives:

2x = -π/4

x = -π/8

Therefore, the solutions for x in the interval 0 ≤ x ≤ 2π are x = π/8 and x = -π/8.

To buy down the quoted interest rate from 4.75% to 4.5% will cost Trystan and Kendall $4,800 after the down payment.

The down payment refers to the initial cash payment for the purchase of an item on mortgage.

The down payment is required by the financier to evaluate the buyer's financial readiness.

The cost of the new home = $300,000

Down payment = 20% or $60,000 ($300,000 x 20%)

Mortgage loan required = $240,000 ($300,000 - $60,000)

Bank quoted interest rate = 4.75%

Desired interest rate = 4.5%

Difference in interest rate = 0.25% (4.75% - 4.5%)

Rate of buy down of the quoted interest per point = 0.125%

The number of points to buy down the interest rate = 2 (0.25/0.125)

The cost of each point = 1% of $240,000 = $2,400

The total cost of 2 points = $4,800 ($2,400 x 2)

A survey asked 1000 recently retired people about the number of different vehicles they owned during their working lives. The goal is to find the mean and standard deviation of the probability distribution based on the collected data.

To calculate the mean and standard deviation of the probability distribution, the data collected from the survey can be analyzed using Excel. The probability distribution table represents thre fequency distribution of the number of vehicles owned. Each value of the number of vehicles owned corresponds to a specific probability.

In Excel, the mean can be calculated by multiplying each value by its corresponding probability, summing up the products, and dividing by the total number of values. This yields the average number of vehicles owned.

The standard deviation can be calculated by using the formula =STDEV.P(range), where the range is the data set of the number of vehicles owned. This formula calculates the standard deviation of a population, assuming that the data represents the entire population of retired individuals.

By applying these calculations in Excel, rounding the results to three decimal places, the mean and standard deviation of the probability distribution can be determined.

True. The k-nearest neighbor method can be used to classify a categorical outcome.

The k-nearest neighbor (k-NN) algorithm is a popular machine learning algorithm used for both classification and regression problems. In the case of classification problems, the k-NN algorithm works by finding the k data points in the training set that are closest to the input data point and then classifying the input data point based on the majority class of those k neighbors.

For example, if we have a dataset of flowers with different features such as petal length, petal width, and sepal length, and we want to classify a new flower based on these features, we can use the k-NN algorithm. By finding the k-nearest neighbors of the new flower in the dataset, we can determine the majority class of those neighbors and classify the new flower accordingly.

Since classification involves predicting a categorical outcome, the k-NN algorithm can be used for this purpose. Therefore, the statement that the k-nearest neighbor method can be used to classify a categorical outcome is true.

The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a conversion factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn.

(a) The given units can be converted as follows: 6 glints = 1 filn...

(1)12 grees = 1 zool...

(2)2 grees = 10 twibbs...

(3)5 grees = 1 bic...

(4)Note that the grees are in both the numerator and denominator of the second unit conversion factor (3). Hence we can cancel out the grees by using it twice in the numerator and denominator. Now using the given conversion factors in equation (1), we get:

7 glint/twibb=7 glint/ (10 grees/2 grees)=14 glint/10 grees=14 glint/ (5 grees/12 grees)=16.8 filn/strord

(b) We need to convert the result of part (a) from filn/strord to megafiln/strord.

1 mega = 106

Thus 1 megafiln = 106 filn

16.8 filn/strord = (16.8 filn/strord) x (1 megafiln/106 filn) = 1.68 x 10-5 megafiln/strord

The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn.

(a) We can rewrite 32 as 2^5, so we have:

8^(2x) = (2^5)^(x+3)

Simplifying the right side, we get:

8^(2x) = 2^(5x+15)

(b) Now we can use the fact that 8 is 2^3, so we can rewrite the left side as (2^3)^(2x) = 2^(6x), giving us:

2^(6x) = 2^(5x+15)

Since the bases are equal, we can equate the exponents and solve for x:

6x = 5x + 15

x = 15

Therefore, the solution is x = 15.
