I need help with d
The data in the table represent the ages of the winners of an award for the past five years. Use the data to answer questions (a) through (e). (Assume that sampling is without replacement.) 41 36 O 47 44 39 a. Find the population mean age of the five winners. u= 41.4 years b. For samples of size 3, construct a table of all possible samples and their sample means.
