The selling price of new homes in a city over a year was normally distributed with a mean of $115,000 and a standard deviation of $25,000. A random sample of 16 new home sales from this city was taken. Describe the sampling distribution of the sample mean (indicate center, spread, shape). mean = $115,000, standard deviation = $6,250, and shape = exactly normal mean = $115,000, standard deviation = $2,500, and shape = exactly normal mean = $115,000, standard deviation = $25,000, and shape = exactly normal mean = $115,000, standard deviation = $6,250, and shape = unknown mean = $115,000, standard deviation = $2,500, and shape = approximately normal by the Central Limit Theorem BO MA W P DO
