28BSC: Large Data Sets from Appendix B. In Exercises, refer to the indicated data set in Appendix B. Use computer software or a calculator to find the means and medians. IQ Scores - Refer to Data Set 6 in Appendix B and use the listed IQ scores. IQ tests are designed so that the mean IQ of the population is 100. Does the sample mean suggest that the sample is conBsistent with the population?
ANSWER:Solution 28BSC: The goal is to find the mean and median of the given data set and to determine whether the sample mean suggests that the sample is consistent with the population. Step 1 of 2: Define the two terms: mean and median. The ean is the average of a set of data values. To calculate the mean, add together all the data values and then divide the sum by the total number of values in the set. The median is the “middle” observation in a data set. To find the median, we arrange the observations in order from smallest to largest value. If there is an odd number of observations, the median is the middle value. If there is an even number of observations, the median is the average of the two middle values.
