About 32 people have hemoglobin levels less than 13, and about 100 people have hemoglobin levels greater than 14.
<h3>What is a normal distribution?</h3>
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
