Suppose that a condom sample of 16 recently sold houses in a certain city has a mean sales price of $275,000, with a standard deviation of $10.000. Under the assumption that house prices are normally distributed. find a 95% confidence interval for the mean sales price of all houses in this city. Give the 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 lower Limit: $4 X 5 Upper TIL: $17
