The partially filled contingency table gives the frequencies of the data on age (in years) and sex from the residents of a retirement home.
Age (yrs)

What is the proportion of male residents in the age group 60-69?

0.50

0.44

0.35

0.60

0.55

Solution

Total number of males = 11 + 9 + 5 = 25

Number in 60-69 = 11

Thus, proportion = 11 / 25

= 0.44

Hope this helps.
