Question

Use data on college students collected from the American College Health Association-National College Health Assessment survey \(^{18}\) conducted in Fall 2011 . The survey was administered at 44 colleges and universities representing a broad assortment of types of schools and representing all major regions of the country. At each school, the survey was administered to either all students or a random sample of students, and more than 27,000 students participated in the survey. Binge Drinking Students in the ACHANCHA survey were asked, "Within the last two weeks, how many times have you had five or more drinks of alcohol at a sitting?" The results are given in Table \(2.13 .\) Table 2.13 In the last two weeks, how many times have you had five or more drinks of alcohol? $$\begin{array}{l|rr|r}\hline & \text { Male } & \text { Female } & \text { Total } \\\\\hline 0 & 5402 & 13,310 & 18,712 \\\1-2 & 2147 & 3678 & 5825 \\\3-4 & 912 & 966 & 1878 \\\5+ & 495 & 358 & 853 \\\\\hline \text { Total } & 8956 & 18,312 & 27,268 \\\\\hline\end{array}$$ (a) What percent of all respondents answered zero? (b) Of the students who answered five or more days, what percent are male? (c) What percent of males report having five or more drinks at a sitting on three or more days in the last two weeks? (d) What percent of females report having five or more drinks at a sitting on three or more days in the last two weeks?

Short answer

Accordingly, the answers are: (a) Approx. 68.7%, (b) Approx. 58.03%, (c) Approx. 15.72%, (d) Approx. 7.23%

Step-by-step solution

Compute Total Number of Respondents

To begin with, the total number of respondents is needed to calculate the percentages. Looking at the end of the table, it can be seen that the total number of respondents is 27,268.

Calculate the Percentage of Respondents who Answered Zero

The no. of participants who answered zero is given as 18,712. So percentage can be calculated as \((18712/27268)*100\) in part (a).

Calculate the Percentage of Male Students who Repeated Binge Drinking

In part (b), for students who answered five or more days, the number of male students who responded is 495, so percentage can be calculated as \((495/853)*100\).

Calculate the Percentage of Male Students who Reported Heavy Consumption

In part (c), the number of male students who drank five or more drinks three or more days is the sum of the third and fourth rows, 912 + 495 = 1407. The percentage can be calculated as \((1407/8956)*100\).

Calculate the Percentage of Female Students who Reported Heavy Consumption

Lastly in part (d), the number of female students who drank five or more drinks three or more days is the sum of the third and fourth rows, 966 + 358 = 1324. The percentage can be calculated as \((1324/18312)*100\).
