Assume that the height of men are normally distributed with a mean of 69.8 inches and a standard deviation deviation of 3.5 inches. If 100 men are randomly selected, find thr probability that they have a mean height greater than 69 inches.

Answer 1

Solution: meas s Given 69.8 standard deviation 0 : 3,5" Random Sample 1:100 probability that they have a mean height greater than 69 inches P(x>69) - P(x269) 69-69.8 :7-pale 3.5ico 1-P (za l-P(22 - 2.2857) < : -0.8 0.35 -ܐ :/- 0,0111 . 0,9889 .: P(x369)- 0.9886 4" option is Couvert
