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.

Step-by-step explanation:

Given that Alice works at a health care facility. She has measured the hemoglobin levels of 200 people.

Let X be the hemoglobin level of a person

Then X is normal (14, 1)

For X<13, we have

z<-1

Hence probability = 0.16

i.e. 16% or32 people will have hemiglobin below 13.

People who have greater than 14

X>14 means z>0

Hence exactly 50% or 100 people will have hemiglobin levels >14

step-by-step explanation:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
