Suppose your statistics instructor gave six examinations during the semester. You received the following exam scores (percent correct): 83, 76, 82, 84, 89, and 73. The instructor decided to randomly select two exam scores, compute their mean, and use this score to determine your final course grade. a. Compute the population mean. This is your average grade based on all of your grades. (Round your answer to 2 decimal places.) Population mean b. Compute the population standard deviation. (Round your answer to 2 decimal places.) Population standard deviation c. How many different scores could be calculated if your instructor decided to random sample two of your exam scores? Number of different samples
