Chandler bought 16 pineapples from the supermarket and calculated the average weight of them. What
is the probability that the average weight is between 4.5 and 5.2 pounds?

Solution

mean = 16 * 0.5 = 8

SD = srqt ( 16*0.5*0.5 ) = 2

P( 4.5 - 8 / 2 < z < 5.2-8 / 2)

P( -1.75 < z < -1.4) = 0.0808-0.0401 = 0.0407
