Listed below are the systolic blood pressures (in mm Hg) for a sample of men aged 20-29 years and for a sample of men aged 60-69 years. Find the coefficient of variation for each of the two sets of data, then compare the variation. Round results to one decimal place. Men aged 20-29: 117 122 129 118 131 123 Men aged 60-69: 130 153 141 125 164 139 O A. Men aged 20-29: 4.6% Men aged 60-69: 10.2% There is substantially more variation in blood pressures of the men aged 60-69. O B. Men aged 20-29: 4.4% Men aged 60-69: 8.3% There is substantially more variation in blood pressures of the men aged 60-69. O C. Men aged 20-29: 4.8% Men aged 60-69: 10.6% There is substantially more variation in blood pressures of the men aged 60-69. O D. Men aged 20-29: 7.6% Men aged 60-69: 4.7% There is more variation in blood pressures of the men aged 20-29
