Dmitry [639]

Answer:

Option H

Step-by-step explanation:

<u>Step 1:  Determine which option is correct</u>

Option F:  The mode/most common number in Store 1 is 2 which the mode of Store 2 is 1.  So... the first option is not correct.

Option G:  The range for both of the data sets are 6.  So... the second option is not correct.

Option H:  The mean/average of Store 1 is 2.9 which the mean/average for Store 2 is 2.  So... this option is correct because store 1 does have a higher mean than store 2.

Answer:  Option H

What is the slope of a line that passes through the points (61,-17) and (62,64)
4vir4ik [10]

Answer:

m = 81

Step-by-step explanation:

Recall that slope m = rise / run.

As we go from (61,-17) to (62,64), the horizontal measurement (x) increases by 1 and the vertical measurement (y) increases by 81.

Thus, the desired slope is

        81

m = ------ = 81

          1

The following data was collected to explore how the average number of hours a student studies per night and the student's GPA af
Mekhanik [1.2K]

Answer:

Pvalue = 0.1505

y = 0.550x1 + 3.600x2 + 7.300

Step-by-step explanation:

Given the data :

Study Hours GPA ACT Score

5 4 27

5 2 18

5 3 18

1 3 20

2 4 21

Using technology, the Pvalue obtained using the Fratio :

F = MSregression / MSresidual = 30.228571/ 8.190476 = 3.69

The Pvalue for the regression equation is:

Using the Pvalue from Fratio calculator :

F(1, 3), 3.69 = 0.1505

Using the Pvalue approach :

At α = 0.01

Pvalue > α ; Hence, we fail to reject H0 and conclude that ; There is not enough evidence to show that the relationship is statistically significant.

The regression equation :

y = A1x1 + A2x2 +... AnXn

y = 0.550x1 + 3.600x2 + 7.300

x1 and x2 are the predictor variables ;

y = predicted variable
