An experiment to study the relationship between x = time spent exercising (minutes) and y = amount of oxygen consumed during the exercise period resulted in the following summary statistics.

a. Estimate the slope and y intercept of the population regression line.

b. One sample observation on oxygen usage was 757 for a 2-minute exercise period. What amount of oxygen consumption would you predict for this exercise period, and what is the corresponding residual?

c. Compute a 99% confidence interval for the average change in oxygen consumption associated with a 1- minute increase in exercise time.
