PLEASE ANSWER ALL THE PARTS OF THE QUESTION (THIS IS NOT A GRADED ASSIGNMENT) 1. Suppose the distribution of cholesterol levels in a population of men is approximately normally distributed with a mean of 200 mg/dL and a standard deviation of 32 mg/dL. A. What is the standard deviation of the sampling distribution of ˉxˉ for n=25? Write your answer as a decimal value rounded to four decimal places. B. What condition allows us to say that the value in part (A) is approximately true? C. What is the shape of the sampling distribution of ˉxˉ for n=25? D. What condition allows us to answer as we did in part (C)? E. You take a random sample of 25 males from this population and find the average level of the sample to be 188 mg/dL. How unusual is this sample? Show your work (conditions, mechanics, and context)
