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.

Select one:

		Men aged 20-29: 5.5% Men aged 60-69: 10.5% There is substantially more variation in blood pressures of the men aged 60-69.
		Men aged 20-29: 5.3% Men aged 60-69: 10.1 % There is substantially more variation in blood pressures of the men aged 60-69.
		Men aged 20-29: 5.0% Men aged 60-69: 8.2% There is substantially more variation in blood pressures of the men aged 60-69.
		Men aged 20-29: 8.7% Men aged 60-69: 4.6% There is more variation in blood pressures of the men aged 20-29.
