Question

Alexis works at a health care facility. She has measured the hemoglobin levels of 400 people. The data follows a normal distribution with a mean of 16 g/dL and a standard deviation of 2. What percentage of people had a hemoglobin level of 18 g/dL or higher?

Answer 1

Step-by-step explanation: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 (32) people have hemoglobin levels less than 13, and about (100) people have hemoglobin levels greater than 14.

Answer 2

Explanation:

Let X be the hemoglobin level

x is normal with (16,2)

people having hemoglobin levels >18g/dl

P(X>18) = P(Z<(8-14)/2) =

"Given that 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.

Let X be the hemoglobin level

X is normal with (14, 1)

People having hemoglobin levels <13

would be

P(X<13) = P(Z<(13-14)/1) =0.16

Hence for 200 people no of people having less than 16 = 0.16(200) =32

P(X>14) = 0.5

Hence no of people =100"
