Suppose Stat I students ages follow a skewed right distribution with a mean of 24 years old and a standard deviation of 2 years old. If we randomly sampled 150 students, which of the following statements about the sampling distribution of the sample mean age is incorrect?
-The mean of the sampling distribution is approximately 24 years old.
-The standard deviation of the sampling distribution is equal to 2 years old.
-The shape of the sampling distribution is approximately normal.
-None of the above statements are correct.
The shape of the sampling distribution is approximately normal.
The solution gives the answer of a question based on sampling distribution.
