Question

Alice works at a health care facility. She has measured the hemoglobin levels of 200 people. The data follows a normal distribution with a mean of 14 g/dL and a standard deviation of 1.
From the given data, we can conclude that about people have hemoglobin levels less than 13, and about people have hemoglobin levels greater than 14.

Answer 1

This is a normal distribution with the mean of 14 g/dL and a standard deviation of 1 g/dL.
For less than 13 ( 13 = mean - 1 standard deviation and less ):
16 % of 200, 0.16 * 200 = 32 people.
For greater than 14 ( mean and greater ):  50 % of 200 = 100 people.  

Answer 2

It's about like 100 people I think.
