Problem 1 (grade point average)refer tograde point averagedata in problem 1.19. the data can be downloaded or read intorfrom: the variables from left to right are, y= gpa, x1= act score, x2= intelligence test score, x3= highschool class rank percentile.

a. prepare a box plot for the act scoresx1i. are there any noteworthy features in this plot? the boxplot shows a fairly symmetric distribution with large tails indicating a bell-shaped curve.
b. prepare a dot plot of the residuals. what information odes this plot provide?

answer is:

1.75 pounds

b. hannah is playing with her cousin at

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
