Health care issues are receiving much attention in both academic and political arenas. A sociologist recentlyconducted a survey of citizens over 60 years of age whose net worth is too high to qualify for governmenthealth care but who have no private health insurance. The ages of 25 uninsured senior citizens were as follows: $$\begin{array} { l l l l l l l l l l l l l }
68 & 73 & 66 & 76 & 86 & 74 & 61 & 89 & 65 & 90 & 69 & 92 & 76 \
62 & 81 & 63 & 68 & 81 & 70 & 73 & 60 & 87 & 75 & 64 & 82 &
\end{array}$$ Suppose the mean and standard deviation are 74.0 and 9.7, respectively. If we assume that the distribution ofages is bell shaped, what percentage of the respondents will be between 64.3 and 93.4 years old?
A) approximately 81.5%
B) approximately 68%
C) approximately 95%
D) approximately 83.9%
