2. Suppose that the student taking 22 credit hours in the data set in the previous question was actually taking 28 credit hours instead of 22 (so we would replace the 22 in the data set with 28). Indicate whether changing the number of credit hours for that student would make each of the following summary statistics increase, decrease, or stay about the same. Don't calculate these quantities. This question can be answered without any calculations and you will lose points if you provide any type of calculations. (1 point each) a. Mean b. Median c. Range d. Standard Deviation 1
