We are given the equation for the height.

On the graphic, height and width are related. Choosing a point, it is possible for us to find the value of the constant.

Doing this, we get that the value of the constant is: 100, given by option C.

Height equation:

$H=\frac{C}{W}$

In which H is the height, C is the constant and W is the width.

Choosing a point and finding the constant:

We choose a point given in the graphic, I will choose (4,25), which means that when $W =4, H =25$ . We use this to find the constant. So

$H=\frac{C}{W}$

$25 = \frac{C}{4}$

$C=25$ × $4=100$

Thus, the constant is 100, and the answer is given by option c.

A professor obtains SAT scores and freshman GPA for a group of 15 college students with the hope that she can predict GPA using

kramer

The hypothesis test analyzes the null and alternative hypothesis of the

plausibility of a correlation between the SAT scores and GPA.

The hypothesis test that would be appropriate is a hypothesis test that checks that the slope of the regression line is not zero.

Reasons:

The data collected by the professor = The scores of the college students

The type of scores collected = SAT scores, and GPA scores

The test that would be appropriate for the example, is the test for the

existence of a significant linear relationship between the input variable

(the SAT scores) and the output variable (the GPA)

The test is known as the test for the slope of the regression line

The equation of the regression line is; Y = B₀ + B₁·X

Where;

Y = The value of the GPA score (The dependent variable)

X = The value of the SAT score (The independent variable)

The test aims to check that the value the slope of the regression line is

much different from zero, such that there exist a correlation.

Answer:

Mean = 10

Variance = 30.89

Standard Deviation = 5.56

Step-by-step explanation:

Find the Mean, Variance and Standard deviation

6, 14, 8, 2, 11, 7, 12, 4, 18, 18

Step 1

We rearrange the data and find the Mean

2, 4, 6, 7, 8, 11, 12, 14, 18, 18

Mean = Sum of values/Number of values

= 2 + 4+ 6+ 7+ 8 + 11 + 12 + 14 + 18 +18/10

= 100/10

= 10

Step 2

We find the variance of this sample days ma

Variance = (x - Mean)²/n - 1

n = 10

Hence,

=( (2 - 10)² +(4 - 10)²+ (6 - 10)²+ (7 - 10)² + (8 - 10)² + (11 - 10)² + (12 - 10)² + (14 - 10)² + (18 - 10)² +(18 - 10)²) /10 -1

= ( 64 + 36 + 16 + 9 + 4 + 1 + 4 + 16 + 64 +64)/9

= 278/9

= 30.88888889

Approximately = 30.89

Step 3

Standard Deviation = √Variance

= √30.89

= 5.5578772926

Approximately = 5.56
