The weights of ripe watermelons grown at Mr. Smith's farm are normally distributed with a standard deviation of 2.7 lb. Find the mean weight of Mr. Smith's ripe watermelons if only 9% weigh less than 12 lb. (Give your answer correct to one decimal place.)

Expert Solution

so, the mean is 15.5 lb (corrected to one decimal place)
