Find the Coefficient of Variation for Each of the Two $\mathrm { mm } \mathrm { Hg }$

question 132

Short Answer

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 $\mathrm { mm } \mathrm { Hg }$ ) for a sample of men aged 20-29 and for a sample of men aged 60-69.

$\begin{array}{llllll}\text { Men aged 20-29: } 117 & 125 & 133 & 118 & 131 & 123 \\\text { Men aged 60-69: } 130 & 151 & 138 & 125 & 164 & 139\end{array}$

A) 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.

B) 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.

C) 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.

D) Men aged 20-29: 5.0%
Men aged 60-69: 8.2%
There is substantially more variation in blood pressures of the men aged $60 - 69$ .

• A) 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.
• B) 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.
• C) 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.
• D) Men aged 20-29: 5.0%
• Men aged 60-69: 8.2%
• There is substantially more variation in blood pressures of the men aged \(60 - 69\).
