5. Consider the partial relative frequency distribution of consumer preferences for four products---W, X, Y, and Z--- that is shown as follows: l Product Relative Frequency | W 0.15 a] Find the relative frequency for product X. b) If 500 consumers were surveyed, give the frequency distribution for these data. c] Construct a percent frequency bar chart for these data. d] If we wish to depict these data using a pie chart, find how many degrees [out of 360) should be assigned to each of the products W, X. Y, and Z. Then construct the pie chart
