Solve the following problems, BOX your final answer. 1. Suppose that the Environmental Protection Agency of a developed country performs extensive tests on all new car models in order to determine their mileage rating. Suppose that the following 35 measurements are obtained by conducting such tests on a particular new car model. EPA MILEAGE RATINGS of CARS (MILEPER GALLON) 36.3 30.1 40.5 36.2 38.5 36.3 41.0 37.0 37.1 39.9 42.1 37.5 40.0 35.6 38.8 43.8 32.9 40.2 35.9 38.6 38.4 39.0 36.7 34.8 38.1 40.5 37.0 37.1 33.9 39.8 37.6 40.2 39.0 31.9 41.1 A. Using 5 intervals, construct frequency distribution table. Use 30.0 as first lower class limit. B. Solve for the Mean, median, mode, variance range and standard deviation. C. Construct Frequency Polygon and Frequency Histogram FINAL ANSWER: (Use 4 decimal places) Mean = Range = Median = Variance Mode = Std. Dev. = 2. The following data are the measures of the diameters of 36 rivet heads in 1/1000 of an inch. 6.721 6.779 6.826 6.709 6.782 6.709 6.621 6.754 6.661 6.668 6.644 6.734 6.803 6.728 6.765 6.760 6.689 6.668 6.625 6.728 6.766 6.706 6.767 6.678 6.709 6.728 6.749 6.819 6.799 6.784 6.666 6.765 6.765 6.769 6.786 6.721 a) Using 6 intervals, make a frequency distribution table. b) Compute for the mean median, mode variance and standard deviation. c) Construct Frequency Polygon FINAL ANSWER: (use 4 decimal places) Mean = Range = Median = Variance = Mode = Std. Dev. = 3.
