Show transcribed image text Following is a list of the number of hazardous waste sites in each of the 50 states of the United States as of April 1995. The data are taken from The World Almanac and Book of Facts 1996 (World Almanac Books, Mahwah NJ, 1996). The list has been sorted into numerical order 4 2 10 13 19 20 39 6 12 17 29 8 12 18 30 96 102 107 8 12 18 9 12 19 37 4 10 13 10 16 24 58 17 25 15 22 23 40 38 a) Draw a stem and leaf plot of this data using leaf unit =1, with two leaf categories per stem. Also find the increment b) Find the sample mean, sample standard deviation and sample median of the number of hazardous waste sites in each of the 50 states. (You can use your calculator to get Σ x and Σ. but show your work in all your calculations) c) What proportion of hazardous waste sites is more than one standard deviation greater than the mean? d) Construct a frequency table and display it as a histogram using a class width of 10. [Recall: LCB is included in the class interval whereas UCB is not included.] Your first class should be [0, 10) e) What proportion of the 50 states has between 40 and 80 hazardous waste sites? (include 40 and 80) f) How would you describe the shape of the histogram? (right skewed, left skewed, normal or inconclusive) g) Find 3 quartiles (i.e. Q1, Q2 (median). Q3l and construct a boxplot for these data. Does the boxplot show any outliers? If so, state them
