The weights (in pounds) of the ten acrobats are shown below, 196, 163, 173, 139, 142, 87, 182, 136, 149, 177. The sample mean is lbs. The standard deviation is lbs. b) The formula for Z-score is, where x is the raw score. It is assumed that the data is normally distributed. The random variable represents weights in pounds. The percentage of the data lies within one standard deviation of the mean is calculated as, Therefore, The percentage of the data that lies within one standard deviation of the mean is approximately 68%.The is calculated using the Excel formula "" as follows, The Excel snip is provided below, The is calculated using the Excel formula "" as follows, The Excel snip is provided below, c) The percentage of the data lies within two standard deviations of the mean is calculated as, Therefore, The percentage of the data that lies within one standard deviation of the mean is approximately 95%.The is calculated using the Excel formula "" as follows, The Excel snip is provided below, The is calculated using the Excel formula "" as follows, The Excel snip is provided below, b) The percentage of the data that lies within one standard deviation of the mean is approximately 68%.c) The percentage of the data that lies within one standard deviation of the mean is approximately 95%.
