Suppose it is know from past research that the average cold lasts 5.7 days with a standard deviation of 2.3. A researcher takes an SRS of 50 children at an elementary school who had a cold this past winter and found out how long their cold symptoms lasted. Assuming that the Central Limit Theorem applies, give the sampling distribution of X for n = 50.
