Math Problem Statement
Suppose that 100 items are drawn from a population of manufactured products and the weight, X, of each item is recorded. Prior experience has shown that the weight has a non- normal probability distribution with u - 3 ounces. Which of the following is true about the sampling of X? = 8 ounces and o a. Its mean is 8 ounces b. Its standard error is 0.3 ounces. c. Its shape is approximately normal d. All of these choices are true.
