2. Which of the following statements defines the 97.5th percentile value for a data sample, regardless of the sample data distribution? The value that is 97.5% larger than the sample mean. The value such that 2.5% of the sample observations are larger than this value, and 97.5% of the sample observations are smaller than this value. The value such that 97.5% of the sample observations are larger than this value, and 2.5% of the sample observations are smaller than this value. This value always corresponds to the sample mean plus 2 standard deviations.

Suppose your statistics professor gave six examinations during the semester. You received the following exam scores (percent correct): 79, 84, 82, 82, 84 and 77. To compute your final course grade, the professor decided to randomly select two exam scores, compute their mean, and use this score to determine your final course grade.i. List all possible samples of size 2 and compute the mean of each.ii. Compare mean of sample means to the population mean.

3. The amount of time (in minutes) it took each individual in a sample of athletes to run a mile was recorded. In this particular sample, most of the athletes were able to run the mile quickly, but there were a small number of athletes who were not fast runners and needed more time to complete the mile. Two measures of center were computed for this sample: 12.9 minutes and 9.5 minutes. One of these measures is the mean and one is the median. Which measure must be the mean? A. The mean is 9.5 minutes because the distribution of running times would be skewed to the left. B. The mean is 9.5 minutes because the distribution of running times would be skewed to the right. c. The mean is 12.9 minutes because the distribution of running times would be skewed to the left. D. The mean is 12.9 minutes because the distribution running times would be skewed to the right.
