What is the probability that themean height for the sample is greater than 65 inches? Assume o = 2.57The probability that the mean height for the sample is greater than 65 inches is(Round to four decimal places as needed.)

Answer 1

step 1

Find out the z-score

so

z=(65-64.3)/2.57

using a z-score calculator

the probability is equal to

P=0.3927
