We suspect that automobile insurance premiums (in dollars) may be steadily decreasing

with the driver's driving experience (in years), so we choose a random sample of drivers

who have similar automobile insurance coverage and collect data about their ages and

insurance premiums.

A. matched pairs t-test

B. two-sample t-test

C. ANOVA

D. chi-squared test for independence

E. inference for regression

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

it’s the first one your welcome
