In a study of reaction times, the time to respond to a visual stimulus (x) and the time to respond to an auditory stimulus (y) were recorded for each of 10 subjects. Times were measured in thousandths of a second. The results are presented in the following table.

a. Compute the least-squares regression line for predicting auditory response time (y) from visual response time (x).

b. Construct a 95% confidence interval for the slope.

c. Test H0: β1 = 0 versus H1: β1 ≠ 0.

Can you conclude that visual response is useful in predicting auditory response?

Use the α = 0.01 level of significance.
