The Reaction workbook contains reaction times from the first-round heats of the 100-meter race at the 1996 Summer Olympic games. Reaction time is the time elapsed between the sound of the starter’s gun and the moment the runner leaves the starting block. The workbook also contains the heat number, the order of fi nish, and the fi nish group (1st through 3rd, 4th through 6th, and so forth). a. Open the Reaction workbook from the Chapter04 folder and save it as Reaction Statistics. b. Calculate univariate descriptive statistics for the reaction times listed. What are the average, median,

The workbook also contains the heat number, the order of fi nish, and the fi nish group (1st through 3rd, 4th through 6th, and so forth). a. Open the Reaction workbook from the Chapter04 folder and save it as Reaction Statistics. b. Calculate univariate descriptive statistics for the reaction times listed. What are the average, median, minimum, and maximum reaction times? c. Create a boxplot of the reaction times. Are there any moderate or extreme outliers in the distribution? How would you characterize the shape of the distribution? d. Create a stem and leaf plot of the reaction times. e. Reaction times are important for determining whether a runner has false started. If the runner’s reaction time is less than 0.1 second, a false start is declared. Where would a reaction time of 0.1 second fall on your boxplot: as a typical value, a moderate outlier, or an extreme outlier? Does this definition of a false start seem reasonable given your data? f. Is there an association between reaction time and the order of finish? Calculate descriptive statistics for the reaction times broken down by order of finish. Pay particular attention to the mean and the median. g. Create a boxplot of the reaction times broken down by order of finish. Is there anything in your descriptive statistics or boxplots to suggest that reaction time plays a part in how the runner finishes the race? h. Save your changes to the workbook and then write a report summarizing your observations and calculations.
