Suppose that a random sample of ten recently sold houses in a certain city has a mean sales price of $285,000, with a standard deviation of $5000. Unde assumption that house prices are normally distributed, find a 95% confidence interval for the mean sales price of all houses in this community. Then find lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to the nearest whole number. (If necessary, consult a list of formulas.) Lower limit: $|| Upper limit: S
