Consider the approximately normal population of heights of male college students with mean ? = 68 inches and standard deviation of ? = 4.8 inches. A random sample of 12 heights is obtained.

Find the proportion of male college students whose height is greater than 72 inches. (Round your answer to four decimal places.)

Find the mean of the x distribution. (Round your answer to the nearest whole number.)




(ii) Find the standard error of the x distribution. (Round your answer to two decimal places.)




(e) FindP(x > 68). (Round your answer to four decimal places.)




(f) FindP(x < 63). (round="" your="" answer="" to="" four="" decimal="">
