10 points y=-315.67x + 8986.5 r= -0.951 4,000 3,500 3,000 2,500 car insurance policy cost (dollars) 2.000 1,500 1,000 18 19 20 22 23 24 25 age (years) Every 23-year-old in this group has a lower cost of car insurance than the 18-year- olds. Monthly phone bill cost tends to increase as age of the policyholder increases The value of the correlation coefficient is very close to -1, so there is an association between age and car insurance policy cost The line of best fit indicates that, in general, the cost of the monthly phone bill for a 24-year-old should be on average about $315 less than the cost of a car insurance policy for a 20-year-old. The y-intercept from the line of best fit indicates that if the linear trend holds, the monthly phone bill would be $0 for a person who is about 8.987 years old
