Health care issues are receiving much attention in both academic and political arenas. a sociologist recently conducted a survey of senior citizens whose net worth is too high to qualify for government health care but who have no private health insurance. the ages of 25 uninsured senior citizens were as follows: 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
calculate the variance of the ages of the uninsured senior citizens correct to the nearest hundredth of a year squared.
