Provide an appropriate response.The following data are the snowfall readings (in inches) for a certain city's top ten winter storms. 25?18.7?20?18.7?23.317.6?25?16.4?18.7?15.1(a) Find the mean, median, and mode for the data.(b) Suppose the value 15.1 was actually recorded as 51.1. Compute the mean, median, and mode again using this value. Comment on any differences from the results in part (a).
A. (a) mean: 20.48, median: 19.35, mode: 25; (b) mean: 24.08, median: 21.65, mode: 25; The mean and median are both greater than in part (a). B. (a) mean: 19.85, median: 18.7, mode: 18.7; (b) mean: 23.45, median: 19.35, mode: 18.7; The mean and median are both greater than in part (a). C. (a) mean: 20.48, median: 18.7, mode: 25; (b) mean: 20.48, median: 18.7, mode: 25; The mean, median, and mode are the same than in part (a). D. (a) mean: 19.85, median: 18.7, mode: 18.7; (b) mean: 22.6909091, median: 18.7, mode: 18.7; The mean is greater than the mean in part (a) but the median is the same as in part (a).
