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: 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

Referring to Scenario 3-1, determine which of the following is the correct statement (use the formulas on the lecture notes)

One fourth of the senior citizens sampled are below 65.5 years of age

The middle 50% of the senior citizens sampled are between 65.5 and 73.0 years of age

The mean age of senior citizens sampled is 73.5 years of age

All the above are correct.
