At a large state university, the heights of male students who are interscholastic athletes is approximately normally distributed with a mean of 74.3 inches and a standard deviation of 3.5 inches. the heights of male students who don’t play interscholastic sports (we’ll call them “non-interscholastics”) is approximately normally distributed with a mean of 70.3 inches and a standard deviation of 3.2 inches. you select an srs of 10 interscholastic athletes and 12 non-interscholastics. what is the probability that the sample mean of non-interscholastics is greater than the sample mean of interscholastic athletes?

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
