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 follow:

68 73 66 76 86 74 61 89 65 90 69 92 76

62 81 63 68 81 70 73 60 87 75 64 82

Suppose the mean and standard deviation are 74.0 and 9.7, respectively. If we assume that the distribution of ages is bell-shaped, what will be between 64.3 and 93.4 years old?
