A man trying to improve his health wanted to see if there was a linear relationship between how many miles he ran and his heart rate in beats per minute. After recording how many miles he ran and his heart rate for 12 different days he created this 95% confidence interval for 3 miles (160,180). The twelve different days could be considered a random sample of all of his run days. Which of these options below is the best interpretation of the confidence interval? a. It can be stated with 95% confidence that his average heart rate after running 3 miles is between 160 and 180 beats per minute.
b. 95% of all people who run 3 miles will have a heart rate between 160 and 180 beats per minute.
c. It can be stated with 95% confidence that of the 12 days sampled every time he ran 3 miles his heart rate was between 160 and 180 beats per minute
d. It can be stated with 95% confidence that every time he has a heart rate between 160 and 180 beats per minute he will have just run 3 miles
