Literacy Level At Least Subsistence Group Illiterate Primary Schooling Middle School Shifting cultivators 114 10 45 Settled agriculturists 76 2 53 Town dwellers 93 13 208 a. Graphically depict the data in the table using a stacked bar graph. b. Do a percentage comparison based on the row and column totals. What conclusions do you reach with respect to the relation between literacy and subsistence group? Engin. 3.40 In the manufacture of soft contact lenses, the power the strength of the lens needs to be very close to the target value. In the paper “An ANOM-type test for variances from normal populations’’ [Technometrics 1997 39:274 –283], a comparison of several suppliers is made relative to the consistency of the power of the lens. The following table contains the deviations from the target power value of lenses produced using materials from three different suppliers: Supplier Deviations from Target Power Value 1 189.9 191.9 190.9 183.8 185.5 190.9 192.8 188.4 189.0 2 156.6 158.4 157.7 154.1 152.3 161.5 158.1 150.9 156.9 3 218.6 208.4 187.1 199.5 202.0 211.1 197.6 204.4 206.8 a. Compute the mean and standard deviation for the deviations of each supplier. b. Plot the sample deviation data. c. Describe the deviation from specified power for the three suppliers. d. Which supplier appears to provide material that produces lenses having power closest to the target value? Bus. 3.41 The federal government keeps a close watch on money growth versus targets that have been set for that growth. We list two measures of the money supply in the United States, M2 private checking deposits, cash, and some savings and M3 M2 plus some investments, which are given here for 20 consecutive months. Money Supply Money Supply in trillions in trillions of dollars of dollars Month M2 M3 Month M2 M3 1 2.25 2.81 11 2.43 3.05 2 2.27 2.84 12 2.42 3.05 3 2.28 2.86 13 2.44 3.08 4 2.29 2.88 14 2.47 3.10 5 2.31 2.90 15 2.49 3.10 6 2.32 2.92 16 2.51 3.13 7 2.35 2.96 17 2.53 3.17 8 2.37 2.99 18 2.53 3.18 9 2.40 3.02 19 2.54 3.19 10 2.42 3.04 20 2.55 3.20 a. Would a scatterplot describe the relation between M2 and M3? b. Construct a scatterplot. Is there an obvious relation? 3.42 Refer to Exercise 3.41.
