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. The ages of 25 senior citizens were as follows:



1.    Calculate the arithmetic mean age of the senior citizens. (Note: Use two decimal places, i.e. 12.34)

2.    Determine the median of the senior ages.

3.    Determine the first quartile of the ages of the senior citizens.

4.    Determine the third quartile of the ages of the senior citizens.

5.    Determine the interquartile range of the ages of the senior citizens.

6.    Compute the skewness.

7.    Compute the Kurtosis.

8.    Calculate the variance. (Note: Use two decimal places, i.e. 12.34)

9.    Calculate standard deviation. (Note: Use two decimal places, i.e. 12.34%)

10. Calculate the coefficient of variation.
