Paper planes. In preparation for a regional

Paper planes. In preparation for a regional paper airplane competition, a student tried out her latest design. The distances her plane traveled (in feet) in 11 trial flights are given here. (The world record is an astounding 193.01 feet!) The data were 62, 52, 68, 23, 34, 45, 27, 42, 83, 56, and 40 feet.

 

a) Construct a 95% confidence interval for the mean distance.

b) Based on your confidence interval, is it plausible that the mean distance is 40 ft? Explain.

c) How would a 99% confidence interval for the mean distance differ from your answer in part a? Explain briefly, without actually calculating a new interval.
d) How large a sample size would the student need to get a confidence interval half as wide as the one you got in part a, at the same confidence level?
