A simple random sample of 150 adults is obtained andeach person's red blood cell count (in cellsper microliter) is measured. The sample mean is 4.63. Thepopulation standard deviation for red blood cell counts is 0.54.Which of the following is true regarding the distribution ofsample means?
Question content area bottom
Part 1
Choose the correct answer below.
A.
Even though the distribution of the population data isnot given, the distribution of sample means will beapproximately normal because the sample size is large enoughaccording to the Central Limit Theorem.
B.
The distribution of the population data is notgiven. Therefore, the distribution of sample means will notbe normal.
C.
The distribution of the population data is notgiven. Therefore, the shape of the distribution of samplemeans cannot be known for sure.
D.
The distribution of sample means will not be normal since thesample size is too large.
