Q: The following data (X) represent the number of coupons used over a 6 month time period by a sample of 17 shoppers:
81, 68, 70, 100, 94, 47, 66, 70, 82, 110, 105, 60, 70, 66, 90, 78, 85
Use this sample of data to compute: the mean, the median, the mode, the range, the variance, the standard deviation, and the 90th percentile. Provide a brief explanation of what each measure tells us about the data. Also provide the sum of X and the sum of the squared deviations of X from the mean
