Answer 1

Answer #1

Given that a population has a mean of 143 and a standard deviation 28.

We need to find the mean and standard deviation of the sampling distribution of sample means with sample size n =46.

The mean of the sampling distribution of the sample means is given by,

The standard deviation of the sampling distribution of the sample means is given by,

Hence the mean of the sampling distribution of the sample means with sample size n=46 is,

Hence the standard deviation of the sampling distribution of the sample means with sample size n=46 is,
