4. Develop a 95% confidence interval estimate of the population
mean sales price and population mean number of days to sell for
No Gulf View condominiums. Interpret your results.
5. Assume the branch manager requested estimates of the mean
selling price of Gulf View condominiums with a margin of
error of $40,000 and the mean selling price of No Gulf View
condominiums with a margin of error of $15,000. Using 95%
confidence, how large should the sample sizes be?
6. Gulf Real Estate Properties just signed contracts for two new
listings: a Gulf View condominium with a list price of $589,000
