We suspect that the motor insurance premium (in dollars) can be decreased steadily with Dri driver?

We suspect that the automobile insurance premium (in dollars) can be decreased steadily with the driver's driving experience (years), so choose a random sample of drivers who have similar auto insurance coverage. (a) of matched pairs t-test (b) two-sample t test (c) analysis variance (d) chi-square test for independence (e) of inference for regression

It seems that you want to make an inference of regression. y = premium, and x = age "steadily declining" may imply a linear decline. Setting up a regression, y = beta0 + beta * x + e where e is random error, beta0 is constant and beta is the slope of the relationship. He would like to find beta <0. Finally, you should determine whether beta is significantly different from 0 (one test is usually included in any computer package).
