Problems Calculate the answer to each problem. You may use your calculator. Show some work. 14. Consider the following data showing a sample of 20 car speeds (in mph) on Route 24. First is the raw data, then a frequency distribution in which the bins have been determined but have not yet been filled in. 57 60 62 63 65 65 65 67 68 70 72 74 75 78 79 81 84 86 91 98 Speed (mph) 50-59 60-69 70-79 80-89 90-99 Frequency Relative freq. 1 5% a) The first column has been filled in as an example. Fill in the rest of the columns, both the frequency and relative fre the relative frequency as nt. b) Sketch the relative frequency histogram for this data. c) Circle the shape of this histogram: symmetric skewed skewed right d) Find the range. e) Find the mode. f) Find the median. g) Find the mean. h) Note that the mean is larger than the median. Why is that?
