A recent survey of the Youth Health Information Desk at the Catholic University of the Sacred Heart, Rome, enquired about health awareness among students. The respondents voluntarily attended classes at Sportello Salute Giovari centre. Of the total respondents, \(62.1 \%\) of the male students and \(67 \%\) of female students were aware about the importance of health. Of the respondents in the age group of \(18-21,43.3 \%\) were aware and \(44.5 \%\) of those in the age group of 22-24 were aware. Assuming that only \(62.1 \%\) of male students and \(67 \%\) of female students were aware about the importance of health

a. report the difference between the proportion of male and the proportion of female students who are aware.

b. report the difference between the proportion in the age group of 18-21 and the proportion in the age group of 22-24 who are aware.

c. which variable, gender or age group, seems to have stronger association with health awareness. Explain your reasoning.
