A population has a mean and a standard deviation . Find the mean and standard deviation of a sampling distribution of sample means with sample size n. nothing (Simplify your answer.) nothing (Type an integer or decimal rounded to three decimal places as needed.)

Complete Question

A population has a mean mu μ equals = 77 and a standard deviation σ = 14. Find the mean and standard deviation of a sampling distribution of sample means with sample size n equals = 26

The mean of sampling distribution of the sample mean ( ) is

The standard deviation of sampling distribution of the sample mean ( ) is  

Step-by-step explanation:

From the question we are told that

    The population mean is  

     The  standard deviation is  

     The sample size is  

Generally the standard deviation of sampling distribution of the sample mean ( ) is  mathematically represented as

substituting values  

Generally the mean of sampling distribution of the sample mean ( ) is  equivalent to the population mean i.e  

first one is a: renaming a fraction. second one is c: de-c
