The professor swims Here are data on the time (in minutes) Professor Moore takes to swim 200 yards and his pulse rate (beats per minute) after swimming on a random sample of 23 days:.
(a) Is there statistically significant evidence of a negative linear relationship between Professor Moore’s swim time and his pulse rate in the population of days on which he swims 200 yards? Carry out an appropriate significance test at the alpha = 0.05 level.
(b) Calculate and interpret a 95% confidence inter-val for the slope beta of the population regression line.
