Explanation / Answer

We have been given the params of the normal distribution

We will use normal distribution params to normalize the value of 69 as follows:

P(X>69) = P(Z> 69-63.7 / 2.5) = P(Z>2.12)

NOw use the z tables to take out the pvalue as follows

= 1-.9830 = .0170

Or, 1.7% of people have height greater than 69
