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%.

Sampling frame Ideally, the sampling frame in a sample survey should list every individual in the population, but in practice, this is often difficult.

Suppose that a sample of households in a community is selected at random from the telephone directory. Explain how this sampling method results in under coverage that could lead to bias.

iPhones Suppose 1000 iPhones are produced at a factory today. Management would like to ensure that the phones鈥� display screens meet their quality

standards before shipping them to retail stores. Since it takes about 10 minutes to inspect an individual phone鈥檚 display screen, managers decide to inspect a sample of 20 phones from the day鈥檚 production.

(a) Explain why it would be difficult for managers to inspect an SRS of 20 iPhones that are produced today.

(b) An eager employee suggests that it would be easy to inspect the last 20 iPhones that were produced today. Why isn鈥檛 this a good idea?

(c) Another employee recommends inspecting every fiftieth iPhone that is produced. Explain carefully why this sampling method is not an SRS.

Comparing cancer treatments The progress of a type of cancer differs in women and men. Researchers want to design an experiment to compare three therapies for this cancer. They recruit 500male and 300female patients who are willing to serve as subjects.

(a) Which are the blocks in this experiment: the cancer therapies or the two sexes? Why?

(b) What are the advantages of a randomized block design over a completely randomized design using these 800subjects?

(c) Suppose the researchers had 800male and no female subjects available for the study. What advantage would this offer? What disadvantage?

Treatment 2: It was explained that unforeseen circumstances meant there was only enough work for one person. By 鈥渃hance,鈥� the accomplice was chosen to

be laid off.

Treatment 3: Both students continued to work after the break.

The subjects鈥� work performance after the break was compared with performance before the break. Describe how you would randomly assign the

subjects to the treatments

(a) using slips of paper.

(b) using Table D.

(c) using technology.
