Find the coefficient of variation for each of the two sets of data, then compare the variation. Round results to one decimal place. Listed below are the systolic blood pressures (in mm Hg) for a sample of men aged 20-29 and for a sample of men aged 60-69. Men aged 20-29: 116 122 130 118 131 123 Men aged 60-69: 133 150 140 125 164 139 O A. Men aged 20-29: 8.2% O B. Men aged 20-29: 4.7% Men aged 60-69: 4.4% Men aged 60-69: 7.6% There is more variation in blood pressures of the men aged 20-29. There is substantially more variation in blood pressures of the men aged 60-69. O C. Men aged 20-29: 5.0% O D. Men aged 20-29: 5.2% Men aged 60-69: 9.6 % Men aged 60-69: 10.0% There is substantially more variation in blood pressures of the men aged There is substantially more variation in blood pressures of the men aged 60-69. 60-69
