1. True or False. Justify for full credit. (25 pts) (a) The volume of milk in a jug of milk is 128 oz. The value 128 is from a discrete data set. (b) If the variance from a data set is zero, then all the observations in this data set must be zero. (c) P(A ANDA ) 0, whereA is the complement of A. c c (d) The mean and median for a normal distribution are always the same. (e) In a hypothesis testing, if the p-value is less than the significance level α, we do not have sufficient evidence to reject the null hypothesis. Refer to the following frequency distribution for Questions 2, 3, 4, and 5. Show all work. Just the answer, without supporting work, will receive no credit.
