Question

20. My Notes Ask Your Teacher 01 points | Previous Answers Suppose the 95% confidence interval for the average forearm length of men from the previous problem was (24cm, 27cm). (It wasn't, but that's reasonably close.) How would we then interpret this interval? 95% of all men have a forearm length between 24cm and 27cm. The average forearm length of all men is between 24cm and 27cm 95% of the time. In confidence intervals calculated from many random samples, 95% would contain a sample average forearm length between 24cm and 27cm. 0 In confidence intervals calculated from many random samples, 95% would contain the average forearm length for all men; (24cm, 27cm) is one of those intervals. 95% of men in this sample of 9 men have a forearm length between 24cm and 27cm.
