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.
