Tweet, tweet! What proportion of students at your school use Twitter? To find out, you survey a simple random sample of students from the school roster.

a. Will your sample result be exactly the same as the true population proportion? Explain your answer.

b. Which would be more likely to produce a sample result closer to the true population value: an SRS of 50students or an SRS of 100students? Explain your answer.

Reducing unemployment Will cash bonuses speed the return to work of unemployed people? A state department of labor notes that last year 68%of people who filed claims for unemployment insurance found a new job within 15weeks. As an experiment, this year the state offers $500to people filing unemployment claims if they find a job within 15weeks. The percent who do so increases to 77%. What flaw in the design of this experiment makes it impossible to say if the bonus really caused the increase? Explain your answer.

Reporting weight loss A total of 300 people participated in a free 12-week weight-loss

course at a community health clinic. After one year, administrators emailed each of the

300 participants to see how much weight they had lost since the end of the course. Only

56 participants responded to the survey. The mean weight loss for this sample was 13.6

pounds. Describe how nonresponse might lead to bias in this study. Explain the likely

direction of the bias.

Suppose that 35% of the voters in a state are registered as Republicans, 40% as

Democrats, and 25% as Independents. A newspaper wants to select a sample of 1000

registered voters to predict the outcome of the next election. If it randomly selects 350

Republicans, randomly selects 400 Democrats, and randomly selects 250 Independents,

did this sampling procedure result in a simple random sample of registered voters from

this state?

a. Yes, because each registered voter had the same chance of being chosen.

b. Yes, because random chance was involved.

c. No, because not all registered voters had the same chance of being chosen.

d. No, because a different number of registered voters was selected from each party.

e. No, because not all possible groups of 1000 registered voters had the same chance of

being chosen.

The Willowbrook and hepatitis Bstudies In the 1960s, children entering the Willowbrook State School, an institution for the intellectually disabled on Staten Island in New York, were deliberately infected with hepatitis. The researchers argued that almost all children in the institution quickly become infected anyway. The studies showed for the first time that two strains of hepatitis existed. This finding contributed to the development of effective vaccines. Despite these valuable results, the Willowbrook studies are now considered an example of unethical research. Explain why, according to current ethical standards, useful results are not enough to allow a study.
