Chapter Self Review page 3 3-4 71 The monthly sales for a sample of HiTec Electronic supply stores were organized into a frequency distribution. The mean of weekly sales was computed to be $ 3‚219‚360‚ the median $3‚192‚000‚ and the mode $3‚176‚800. a. Sketch the sales in the form of a smoothed frequency polygon. Note the location of the mean‚ median‚ and mode on the x-axis. - Mode 3‚176‚800 < Median 3‚192‚000 < Mean 3‚219‚360 Therefore‚ b. Is the distribution symmetrical

Despite these advantages‚ the K-S test has several important limitations: 1. It only applies to continuous distributions. 2. It tends to be more sensitive near the center of the distribution
