Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Assume the cholesterol levels in a certain population have mean µ= 200 and standard deviation = 24. The cholesterol levels for a random sample of n = 9 individuals are measured and the sample mean is determined. What is the z-score for a sample mean = 180?

A	-3.75
B	-2.5
C	-0.83
D	2.5

Explanation:

Detailed explanation-1: -The probability that the sample mean cholesterol level is greater than 204 is approximately 0.0047.

Detailed explanation-2: -The cholesterol levels of 20 patients in a hospital with 100 patients. The collection of 20 patients is a subset of the population of 100 patients.
