The Royal Haciendas Resort in Playa del Carmen, Mexico, is thinking of starting a new promotion. When a customer checks out of the resort after spending 5 or more days, the customer would be given a voucher that is good for 2 free nights on the next stay of 5 or more nights at the resort. The marketing manager is interested in estimating the proportion of customers who return after getting a voucher. From a simple random sample of 100 customers, 62 returned within 1 year after receiving the voucher. Please determine the 95% confidence interval estimate of the true population proportion. A- What is the size of the critical score (round to 2 decimal places)?
B- What is the size of the standard error (round to 2 decimal places)?
C- What is the upper boundary of the confidence interval (enter as % rounded to one decimal place, for example, 41.9%)? Do not enter the % sign
D- What is the lower boundary of the confidence interval (enter as % rounded to one decimal place, for example, 41.9%)? Do not enter the % sign
