Pick up to 2 answers
A Every 19-year-old in this group has a lower cost of car insurance than the 18-year-
olds.
B Car Insurance policy cost tends to decrease as age of the driver increases.
C. The value of the correlation coefficient is very close to -1, so there is no association
between age and car insurance policy cost.
D. The line of best fit indicates that, in general, the cost of a car insurance policy for a
21-year-old should be on average, about $315 less than the cost of a car insurance
policy for a 20-year-old
E The intercept from the line of best fit indicates that, if the linear trend holds, a car
insurance policy would be $0 for a person who is about 8,987 years old.
