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

About 32 people have hemoglobin levels less than 13, and about 100 people have hemoglobin levels greater than 14.

What is a normal distribution?

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

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 the number of people has hemoglobin levels less than 13 will be

z = (13 - 14)/1

z = -1

Then the number of people will be

Number of people = 200 P(x < 13)

Number of people = 200 P(z < -1)

Number of people = 200 x 0.15866

Number of people = 31.732

Number of people ≅ 32

A number of people have hemoglobin levels greater than 14 will be

z = (14 - 14)/1

z = 0

Then the number of people will be

Number of people = 200 P(x > 14)

Number of people = 200 P(z > 0)

Number of people = 200 x 0.5

Number of people = 100
