Please give a detailed explanation, not just the response. If possible, a way to work out the problem in Excel is helpful! Thanks in advance! You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable preliminary estimation for the population proportion. You would like to be 98% confident that you estimate is within 1% of the true population proportion. How large of a sample size is required? n=

On May 16, 2017, Verdun Hayes of Somerset, Great Britain set a new Guinness World Record: the oldest ever skydiver. The World War II veteran, who fought on the beaches of Normandy in 1944, set a new record when he skydived at age 101. Suppose the ages of all skydivers follow a normal distribution with mean 52.8 years and standard deviation 10.3 years. Based on this distribution, how old must a skydiver be to fall in the top 1.32% of the distribution? 75.033 75.669 72.242 29.931
