7. Fill in the table with the necessary data to calculate the variance of the sampling distribution of the sample means using the formula: = population mean x= sample mean P(X) = probability of the sample mean where Means (X) P(X) (X - p)² P(X) * ( X - u )² P(X) • (X - u = 8. Draw the histogram of the sampling distribution of the sample means. 9. Answer the following questions: a. What can you say about the mean of the sample means and the mean of the populstion? Answer b. What can you say about the variance of the sample means and the variance of the population Answer
