According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of the individual.

The probability that the person is between 65 and 69 inches is 0.5403

Step-by-step explanation:

Mean height =

Standard deviation =

We are supposed to find What is the probability that the person is between 65 and 69 inches i.e.P(65<x<69)

At x = 65

Z=-0.4

Refer the z table for p value

P(x<65)=0.3446

At x = 69

Z=1.2

P(x<69)=0.8849

So,P(65<x<69)=P(x<69)-P(x<65)=0.8849-0.3446=0.5403

Hence the probability that the person is between 65 and 69 inches is 0.5403

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
