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?

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.

Step-by-step 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) =

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"

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
