Twenty-one young men got a quote for the cost of a car insurance policy. The policy cost and ages of the men are shown in the scatter plot. Select all the statements that are true based on the scatter plot.
A. 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.
B. The y-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.
C. Car insurance policy cost tends to decrease as age of the driver increases.
D. Every 19-year-old in this group has a lower cost of car insurance than the 18-year-olds.
E. The value of the correlation coefficient is very close to -1, so there is no association between age and a car insurance policy cost.
