Question

Female heights in a certain population are distributed normally with a mean of 64 inches and a standard deviation of 2.7 inches

What is the probability that a randomly selected female from this population is more that 70 inches tall?

Group of answer choices

0.056

0.005

0.144

0.013

Answer 1

This is a normal distribution question with

P(x > 70.0)=?
The z-score at x = 70.0 is,

z = 2.2222
This implies that
P(x > 70.0) = P(z > 2.2222) = 1 - 0.9868651037648686

Option D is correct
PS: you have to refer z score table to find the final probabilities.
