Converting the raw data into a 'frequency' distribution is often a first step in making the data more manageable and easier to assess.

A scatterplot is the most helpful graph for demonstrating the connection between two quantitative variables.

Data are listed in rising or decreasing numerical order in a raw data listing. The stem-and-leaf presentation gives more depth than the frequency distribution since it may explain individual data values as well as indicate how many are in each group, or stem.

Bins should have the same width and be mutually exclusive and exhaustive.

A scattergram is a graphical representation of the linkages or correlations that exist between two numerical variables (or covariables), which are shown as points (or dots) for each pair of scores. A scattergraph depicts the intensity and direction of the covariables' connection.

The measures of side lengths of triangle are 10 feet, 15 feet and 20 feet.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given that perimeter of a triangle is 45 feet.

ratio of the lengths of the three sides is 2:3:4

We have to find the measure of each side.

Let us consider the side lengths are 2x, 3x, and 4x.

2x+3x+4x=45

Add the like terms

9x=45

Divide both sides by 9

x=5

Side lengths are 2x = 2×5 = 10 feet,

3x = 3× 5 = 15 feet, and 4x = 4 ×5 = 20 feet.

Hence, the measures of side lengths of triangle are 10 feet, 15 feet and 20 feet.

Allow flyers using racial slurs is not one of the EDI initiatives discussed in the case.

The EDI initiatives discussed in the case include creating an inclusive community where all students thrive, establishing goals to retain underrepresented groups, and implementing a 12-week training program. To create an inclusive community, the school administration must first determine the current state of the campus environment. This can be done through surveys and focus groups, which allow the administration to identify what areas need improvement and how best to address them. Establishing goals to retain underrepresented groups involves setting specific goals for the recruitment and retaining of underrepresented groups, such as increasing the number of faculty or students from underrepresented groups. Finally, implementing a 12-week training program requires developing an educational program to teach students about diversity, equity, and inclusion, and providing the necessary resources to ensure that these lessons are successfully implemented.

The probability of x = 1 is 0.2,x = 2 is 0.3, x = 3 is 0.5

Let X be a random variable with the following probability mass function:

f(x) =

x = 1: 0.2

x = 2: 0.3

x = 3: 0.5

This is indeed a probability mass function because the values of f(x) are all greater than or equal to 0, and the sum of the values of f(x) is equal to

To calculate the probability of x = 1, we can use the formula for probability mass functions: P(X = x) = f(x).

Therefore, the probability of x = 1 is 0.2.

To calculate the probability of x = 2, we can use the same formula: P(X = x) = f(x).

Therefore, the probability of x = 2 is 0.3.

To calculate the probability of x = 3, we can use the same formula: P(X = x) = f(x).

Therefore, the probability of x = 3 is 0.5.

The candidate is an example of a nominal variable. Since candidates are identified through their names, the variable is qualitative in nature. Moreover, since names are all the voters have to go by, there is thus no inherent ordering in the candidates.

Nominal variable is a variable with the lowest level of measurement scale and can only be used for qualitative classification or categorization. That is, these variables can only be measured in terms of whether the characteristics of an object can be distinguished from other characteristics, but we cannot measure or even rank these categories.

For example, we can say that the genders of the 2 people are different, one is female and the other is male. Here we can distinguish the characteristics of the two, but we cannot measure and say which is "more" or which is "less" from the quality represented by the variable.

We can only assign codes/labels to these two characteristics, for example the number 0 for women and the number 1 for men. The code/number label can be exchanged. The code there only serves as a differentiator between the two objects and does not indicate order or continuity. The number 1 does not indicate higher or better than 0.

The area of the triangle is approximately 33.8 square units.

Heron's formula is applicable to all types of triangles. Heron's formula is used to compute the area of a triangle, and every sort of triangle in the world has an area.

So, if the three sides of a triangle are known, Heron's formula may be used to directly determine the area.

We can use the Law of Cosines to find the third side of the triangle, then use Heron's formula to find the area.

First, we find the third side, c:

c^2 = a^2 + b^2 - 2ab * cos(C)

c^2 = 2^2 + 6^2 - 2 * 2 * 6 * cos(127)

c = sqrt(40 - 24 * cos(127))

Next, we use Heron's formula to find the area of the triangle:

s = (a + b + c) / 2

area = sqrt(s * (s-a) * (s-b) * (s-c))

area = sqrt((7.82 + 3) * (7.82 - 2) * (7.82 - 6) * (3))

area = sqrt(45.82 * 5.82 * 1.82 * 3)

area = sqrt(1138.3916)

area = 33.75

Frank's expected utility of wealth function if he takes the bet is U(w) = $1,000,000 + p(ln($100,000)) + (1-p)(ln($900,000)). If Frank accepts the bet, the probability p must be greater than or equal to 0.8.

a) Frank's expected utility of wealth if he takes the bet is U(w) = $1,000,000 + p(ln($100,000)) + (1-p)(ln($900,000))

b) If Frank rejects the bet, his utility of wealth will be U(w) = ln($1,000,000)

c) U(w) = $1,000,000 + p(ln($100,000)) + (1-p)(ln($900,000)) ≥ ln($1,000,000)

p(ln($100,000)) + (1-p)(ln($900,000)) ≥ ln($1,000,000) - $1,000,000

p(ln($100,000)) + (1-p)(ln($900,000) - ln($1,000,000)) ≥ -$1,000,000

p(ln($100,000) - ln($1,000,000)) + (1-p)(ln($900,000) - ln($1,000,000)) ≥ -$1,000,000

p(ln($100,000/$1,000,000)) + (1-p)(ln($900,000/$1,000,000)) ≥ -$1,000,000

p(ln(0.1)) + (1-p)(ln(0.9)) ≥ -$1,000,000

p(ln(0.1)) ≥ -$1,000,000 - (1-p)(ln(0.9))

p ≥ (-$1,000,000 - (1-p)(ln(0.9)))/(ln(0.1))

p ≥ -$1,000,000/(ln(0.1)) - (1-p)(ln(0.9))/ln(0.1)

p ≥ 0.8

d) If Frank's utility of wealth function was less curved, i.e. closer to a straight line, the bound from (c) would be larger. This is because, with a less curved utility of wealth function, Frank would be less risk-averse and therefore more likely to accept the bet.

The standard deviation of the data-set is given as follows:

S(X) = 1.

The mean is given by the sum of all the outcomes multiplied by their respective probabilities, hence:

E(X) = 0 x 0.04 + 1 x 0.43 + 2 x 0.29 + 3 x 0.18 + 4 x 0.05 + 5 x 0.01

E(X) = 1.8.

The standard deviation is given by the square root of the sum of the difference squared between each outcome and the mean, multiplied by their respective probabilities, hence:

S(X) = sqrt[(0 - 1.8)² x 0.04 + (1 - 1.8)² x 0.43 + (2 - 1.8)² x 0.29 + (3 - 1.8)² x 0.18 + (4 - 1.8)² x 0.05 + (5 - 1.8)² x 0.01]
