Question

Vail Resorts would like to send a survey to their guests asking about their satisfaction with the new 2009 website design. They would like to have a margin of error of 65 percent on responses with 95 percent confidence.
(a) Using the conservative approach, what sample size is needed to ensure this level of confidence and margin of error?
(b) If Vail Resorts wanted the margin of error to be only 62.5 percent, what would happen to the required sample size?
