The following data (measured in minutes) are on 40 patients who experience a systematic reaction to beestings. 5.910.5 9.9 14.4 16.5 12.7 11.6 7.9 10.9 13.4 8.6 3.8 11.7 12.5 9.1 9.1 12.3 11.5 7.4 8.8 11.513.6 11.5 10.9 12.9 11.2 15.0 12.7 10.1 14.7 9.911.4 6.2 8.3 8.1 10.5 8.4 11.2 10.4 9.8 (a)Group the data into six classesand obtain a relative frequency distribution. (b)Draw a histogram for the distribution and use it to find the mode. (c)Plot the cumulative frequency curve. Use it to estimate percentage of patients who have experience a reaction within 10 minutes and the median
