Step 1

- It is provided that the age of students is uniformly distributed between 6 and 11 years old. The randomly selected sample,
*n*is 43.

The uniform distribution of *X* can be obtained as:

Step 2

The mean and standard deviation of *X* for the uniform distribution is,

Step 3

b. The Central Limit Theorem states that if the sample size is greater than or equal to 30, the sampling distributions of the mean tend to be normal distribution, irre...
