TABLE 3-1
Health Care Issues Are Receiving Much Attention in Both

Short Answer

TABLE 3-1
Health care issues are receiving much attention in both academic and political arenas. A sociologist recently conducted a survey of citizens over 60 years of age whose net worth is too high to qualify for Medicaid and have no private health insurance. The ages of 25 uninsured senior citizens were as follows:
$$\begin{array} { l l l l l l l l l l l l l } 60 & 61 & 62 & 63 & 64 & 65 & 66 & 68 & 68 & 69 & 70 & 73 & 73 \\74 & 75 & 76 & 76 & 81 & 81 & 82 & 86 & 87 & 89 & 90 & 92\end{array}$$
-Referring to Table 3-1, calculate the variance of the ages of the uninsured senior citizens correct to the nearest hundredth of a year squared.
