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.

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.

Step-by-step explanation:

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

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

it’s supposed to be -4+45=41
