Charity is a big business in the United States. The Web site charitynavigator.com gives information on roughly 5500 charitable organizations, and there are many smaller charities that fly below the navigator's radar screen. Some charities operate very efficiently, with fundraising administrative expenses that are only a small percentage of total expenses, whereas other spend a high percentage of what they take in on such activities. Here is data on fundraising expenses as a percentage of total expenditures for a random sample of 60 charities. 6.1 12.6 34.7 1.6 18.8 2.2 3 2.2 5.6 3.8 2.2 3.1 1.3 1.1 14.1 4 21 6.1 1.3 20.4 7.5 3.9 10.1 8.1 19.5 5.2 12 15.8 10.4 5.2 6.4 10.8 83.1 3.6 6.2 6.3 16.3 12.7 1.3 0.8 8.8 5.1 3.7 26.3 6 48 8.2 11.7 7.2 3.9 15.3 16.6 8.8 12 4.7 14.7 6.4 17 2.5 16.2 a) Construct a frequency table and display it as a histogram using a class width of 10 starting at 0. [Recall: LCB is included in the class interval whereas UCB is not included.] (Be sure to show all of your work, including your frequency chart.) b) What is the proportion of fundraising expenditures less than 10? c) What is the proportion of fundraising expenditures between 10 and 60? d) How would you describe the shape of the histogram? (right skewed, left skewed, normal or inconclusive) Exercise 2 (7 marks) The following data represents body weight (in lbs) for 60 males. 154.25 186.25 179 182 262.75 158.25 173.25 216 200.5 160.25 205 139.25 154 180.5 140.25 168 217 137.25 184.75 205.25 148.75 218.5 212 152.75 184.25 187.75 151.25 247.25 125.25 136.25 210.25 162.75 159.25 191.75 164.25 198 181 195.75 131.5 202.25 133.5 181.5 176 209.25 148 196.75 148.5 201.25 191 183.75 133.25 303.15 135.75 202.5 198.25 211.75 160.75 203 127.5 179.75
