The student records were divided into two groups: male (group 1) and female (group 2). A 93% confidnece interval for pi – P2 was found to be as follows: (0.03, 0.09) Interpret the endpoints of this interval in the context of this problem. Do not use the word "difference" in your answer.For chi-square, what is the difference between observed and expected frequencies? There is no difference: both look at proportions in sample Observed = proportions in sample; expected = proportions in population There is no difference: both look at proportions in population Observed = proportions in population; expected = proportions in sampleWhich of the following statements is correct? A. sigma is the average distance between an individual in a population and the population mean. B. s is the average distance between an individual in a sample and the population mean. C. sigma/√n(or sigma √n if sigma is unknown) is the average distance between a sample mean of size n and the population mean. D. Both A and C.Suppose the mean of X is 94. What does the mean of X become if you multiply X by 1.22? (Use two decimal places, ex: 12.34)
