Researchers working on a small project yielded the following data: 21, 25, 34, 42, 49. Find the Variance of the ESTIMATED POPULATION using the Computational formula. Find the Standard Deviation of the ESTIMATED POPULATION using the Computational formula. (Hint: Use the same numerator from the earlier calculation of the data (SD) of Sample and adjust the denominator to N - 1.)
