Chapter 10: Q.2 (page 621)

Binge drinking Who is more likely to binge drink鈥� 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

Expert verified

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

01

Part (a) Step 1: Given Information

It is given in the question, Who is more likely to binge drink鈥� 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.

02

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.

03

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?

04

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.

Aspirin prevents blood from clotting and so helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anti-clotting drug, named dipyridamole, would be more effective for patients who had already had a stroke. Here are the data on strokes and deaths during the two years of the study.

Number ofpatientsNumber ofstrokesAspirin alone1649206Aspirin + dipyridamole1650157

The study was a randomized comparative experiment.

(a) Is there a significant difference in the proportion of strokes between these two treatments? Carry out an appropriate test to help answer this question.

(b) Describe a Type I and a Type II error in this setting. Which is more serious? Explain

A 96% confidence interval for the proportion of the labor force that is unemployed in a certain city is (0.07,0.10). Which of the following statements about this interval is true?

(a) The probability is 0.96that between 7%and 10%of the labor force is unemployed.

(b) About 96%of the intervals constructed by this method will contain the true proportion of unemployed in the city.

(c) The probability is 0.04that less than 7%or more than 10%of the labor force is unemployed.

(d) The true rate of unemployment lies within this interval 96%of the time.

(e) Between 7%and 10%of the labor force is unemployed96% of the time.

Are teens or adults more likely to go online daily? The Pew Internet and American Life Project asked a random sample of 800 teens and a separate random sample of 2253 adults how often they use the Internet. In these two surveys, 63% of teens and 68%of adults said that they go online every day. Construct and interpret a 90% confidence interval for p1-p2?

Explain why the conditions for using two-sample z procedures to perform inference about p1-p2are not met in the settings

Don鈥檛 drink the water! The movie A Civil Action (Touchstone Pictures 1998) tells the story of a major legal battle that took place in the small town of Woburn, Massachusetts. A town well that supplied water to eastern Woburn residents was contaminated by industrial chemicals. During the period that residents drank water from this well, 16of the 414babies born had birth defects. On the west side of Woburn, 3of the 228babies born during the same time period had birth defects.

48. Did the randomization produce similar groups? First, compare the two groups of birds in the first year. The only difference should be the
chance effect of the random assignment. The study report says: 鈥淚n the experimental year, the degree of synchronization did not differ between
food-supplemented and control females.鈥� For this comparison, the report gives t=-1.05.
(a) What type of tstatistic (one-sample, paired, or two-sample) is this? Justify your answer.
(b) Explain how this value of t leads to the quoted conclusion.
