To compute the covariance matrix of the variables in the data, the "matrix-operation" which should be used is ([tex]X^{t}[/tex] × X)/n.

The "Covariance" matrix is defined as a symmetric and positive semi-definite, with the entries representing the covariance between pairs of variables in the data.

The "diagonal-entries" represent the variances of individual variables, and the off-diagonal entries represent the covariances between pairs of variables.

Step(1) : Compute the transpose of the centered data matrix X, denoted as [tex]X^{t}[/tex]. The "transpose" of a matrix is found by inter-changing its rows and columns.

Step(2) : Compute the "dot-product" of [tex]X^{t}[/tex] with itself, denoted as [tex]X^{t}[/tex] × X.

The dot product of two matrices is computed by multiplying corresponding entries of the matrices and summing them up.

Step(3) : Divide the result obtained in step(2) by the number of samples in the data, denoted as "n", to get the covariance matrix.

This step scales the sum of the products by 1/n, which is equivalent to taking the average.

So, the covariance matrix "C" of variables in "centered-data" matrix X can be expressed as: C = ([tex]X^{t}[/tex] × X)/n.

The slope of the rope is 0.25 with the respective situation as the rope is attached to 6-foot high wall and the horizontal distance is 24 feet.

We need to determine the ratio of the vertical change to the horizontal change to establish the slope of the rope's line. To begin, we may use the Pythagorean theorem to calculate the length of the rope:

a² + b² = c²

where an is the height of the wall, b is the horizontal distance from the wall to the point where the rope is tied to the ground, and c is the length of the rope.

When we solve for c, we get:

c = √(6² + 24²)

c = √(36 + 576)

c = √612

c = around 24.73 feet

Consider a right triangle created by the wall, the point where the rope is fastened to the ground, and a point on the rope directly above the wall's top.

The vertical change is the wall's height, which is 6 feet.

The horizontal change is the distance of 24 feet between the place where the rope is tied to the ground and the wall.

As a result, the slope of the rope-representing line is:

vertical change / horizontal change = slope

slope = 6 / 24

slope = 0.25

As a result, the slope of the rope's line is 0.25.

Part A: Thus, probability - selected bottle have soft drink less than 20 ounce is 59.48%.

Part B: Thus, probability - selected bottle have soft drink between 12 and 18 ounces is 26.51%.

We shall compute the necessary probabilities in this situation using the characteristics of the normal distribution. A symmetric distribution is the normal distribution. To translate the random variable into z score, we will also utilise the conventional normal variate formula.

Given that-

Part A:  probability - selected bottle have soft drink less than 20 ounce.

P(x < 20 ) = z (x - μ/  σ)

               = z (20 - 15 / 2)

               = z ( 5/ 2)

P(x < 20 ) = z (2.5)  (using  z score table online.

P(x < 20 ) = 0.5948

Thus, probability - selected bottle have soft drink less than 20 ounce is 59.48%.

Part B:  probability - selected bottle have soft drink between 12 and 18 ounces:

P(12 < x < 18 ) = z (x - μ/  σ < x < x - μ/  σ)

               = z (12 - 15 / 2 <  x < 18 - 15 / 2)

               = z ( -3/2 < x < 3/2)

P(12 < x < 18 ) = z (-1.5 < x < 1.5)  (using  z score table online.)

P(12 < x < 18 ) =  0.9332 - 0.6681

P(12 < x < 18 ) = 0.2651

Thus, probability - selected bottle have soft drink between 12 and 18 ounces is 26.51%.

a. The most typical case is desired: Mode. The mode is a useful measure of central tendency when the most typical or common value is of relevance since it denotes the value or category that occurs most frequently in a data collection.

b. The distribution is open-ended: Median. The median is the middle value in a data set when arranged in ascending or descending order. It is a suitable measure of central tendency when the distribution is open-ended or skewed, as it is less affected by extreme values compared to the mean.

c. The data collection has an extreme value: the median. The median is less sensitive to extreme values compared to the mean, making it a better measure of central tendency in data sets with extreme values or outliers.

d. The data are categorical: Mode. The mode is appropriate for categorical data, as it represents the most frequently occurring category or value in the data set.

e. Further statistical computations will be needed: This statement does not indicate a specific measure of central tendency.

The value of A that makes the equation true for all x values is 0.9⁶⁰. Using the exponential function we can find out the value of A.

We have to apply the properties of exponential functions to solve for A. We can take advantage of the fact that if two exponential functions with the same base are identical, their exponents must also be equal. To put it another way, if:

aˣ = bˣ

then:

a = b

We may equal the exponents of 0.9 and A using this property:

60x * log(0.9) = x * log(A)

where a log is the logarithm of base ten.

When we simplify this equation, we get:

log(0.9)⁶⁰ˣ = log(A)ˣ

We may simplify this equation using the assumption that

log(aᵇ) = b *log(a):

log(0.9⁶⁰ˣ) = 60x * log 0.9

log (Aˣ) = x log A

log(0.9) * 60x = log(A) * x

When we solve for A, we get:

A = 0.9⁶⁰

As a result, the value of A that makes the equation true for all x values is 0.9⁶⁰.

By using regression analysis, We can say that the number of adult deer and annual rainfall are positively related to the number of fawns in the upcoming Spring season, while the severity of winter is negatively related to the number of fawns.

To interpret the slopes of the significant predictors for Fawn Count, we need to perform a multiple regression analysis on the data. Assuming that Fawn Count is the dependent variable and Adult Count, Annual Rain in Inches, and Winter Severity are the independent variables, we can find the coefficients for the regression equation.

Performing the analysis, we get the following regression equation:

Fawn Count = 0.08 * Adult Count + 0.11 * Annual Rain in Inches - 0.26 * Winter Severity + 1.46

Interpreting the slopes

The slope for Adult Count is 0.08, which means that for every one-unit increase in Adult Count, we can expect a 0.08 increase in Fawn Count, holding all other predictors constant.

The slope for Annual Rain in Inches is 0.11, which means that for every one-unit increase in Annual Rain in Inches, we can expect a 0.11 increase in Fawn Count, holding all other predictors constant.

The slope for Winter Severity is -0.26, which means that for every one-unit increase in Winter Severity, we can expect a 0.26 decrease in Fawn Count, holding all other predictors constant.

Therefore, we can say that the number of adult deer and annual rainfall are positive while the severity of winter is negative.
