1.1 Suppose 50 residents of a large city are randomly selected. Each was asked about his/her main method of transportation. The results are Public Transportation: 11 Personal Motor Vehicle: 33 Bicycle: 5 Other: 1 (a) Construct a bar chart for this dataset. (b) Construct a Pareto chart. 1.3 A researcher determined the weight (in pounds) of 9 first-grade children. The data is listed below. 41, 52, 41, 46, 48, 56, 44, 51, 68 (a) Determine the 5-number summary. (b) Compute the inter-quartile range (IQR). (c) Draw a histogram with 6 bins. Make each bin 5 units wide; let the first bin be [40,45). (d) Describe the shape of the distribution in terms of skewness/symmetry. (e) Draw a boxplot. (f) Draw a stem-and-leaf plot. To create enough stems, split the 40's stem into two pieces: 41 will be the stem for 40 through 44 and 4h will be the stem for 45 through 49. Split the other stems similarly. (g) Compare the shape of the histogram to the stem-and-leaf plot
