The following data represent the number of male and female m

The following data represent the number of male and female murder victims by age in a recent year. Use the data to complete parts a-d. Construct a side-by-side relative frequency bar graph. In the bar graphs below, the blue (left-side) bars represent males and the orange (right-side) bars represent females. Choose the correct graph below. Compare each gender\'s age percentages. Choose the correct answer below. The percentages of male murder victims for each age group are much lower than the percentages of female murder victims for the same age group. The percentages of male murder victims for each age group are much higher than the percentages of female murder victims for the same age group. The percentages of male murder victims for each age group are fairly close to the percentages of female murder victims for the same age group.

Solution

For finding relative frequencies we first need to compute total number of males and total number of females.

Total number of males = 646 + 3403 + 2979 + 2866 + 755 = 10649

Total number of females = 440 + 701 + 716 + 1055 + 439 = 3351

(a) Relative Frequencies for males are given as

Less than 17 : 0.061

17-24 : 0.320

25-34 : 0.280

35-54 : 0.269

55 or older : 0.071

(b) Relative Frequencies for males are given as

Less than 17 : 0.131

17-24 : 0.209

25-34 : 0.214

35-54 : 0.315

55 or older : 0.131

(c) The correct side-by-side relative frequency bar graph is (A)

(d) Answer is (B)
