Question

Binge drinking Who is more likely to binge drink— male or female college students? The Harvard School of Public Health surveys random samples of male and female undergraduates at four-year colleges and universities about whether they have engaged in binge drinking.

(a) Is this a problem with comparing means or comparing proportions? Explain.

(b) What type of study design is being used to produce data?

Short answer

From the given information,

a) The problem is about comparing proportions.

b) Observational study design is being used to produce data .

Step-by-step solution

Part (a) Step 1: Given Information

It is given in the question, Who is more likely to binge drink— male or female college students? The Harvard School of Public Health surveys random samples of male and female undergraduates at four-year colleges and universities about whether they have engaged in binge drinking.

Part (a) Step 2: Explanation

The Harvard School of Public Health reviews irregular examples of male and female students at four-year universities and colleges about whether they have been settled with hard-core boozing.

Since two categories are applied in this problem, that is, Yes or No. It implies that undisturbed data is categorical the mean cannot be calculated here. Thus, it could not be ended that the problem is about proportions.

Part (b) Step 1: Given Information

It is given in the question, The Harvard School of Public Health surveys random samples of male and female undergraduates at four-year colleges and universities about whether they have engaged in binge drinking. We have to find what type of study design is being used to produce data?

Part (b) Step 2: Explanation

Since the observational study does not impact the outcome and in the delivered case no outcomes have been influenced here.

Accordingly, the study is observational.
