Compare for each fan how much he or she consumes in the two games. 14.10 Adding variances requires that the variables are independent. The wind speeds were recorded at sites that were identified as paired and were located nearby, so they are likely to be either high or both low at the same time. The standard deviation of the 1114 pairs of differences in wind speeds is 2.551. 14.12 a) The outliers are very windy days with measurements taken from both sites because they were near each other. SO the difference in wind speeds would be fairly small and consistent, which is what the histogram displays. b) The histogram and summaries based on the differences are more appropriate because these are paired observations and we are interested in comparing the two sites and finding out which one is windier. c) The wind measurements at the same times at two nearby sites are paired.
