Readings Cooper, Ch. 1-5 of Business Research Methods.A statistical consultant was retained by a linen supplier to analyze a survey of hospital purchasing managers. After looking at the data, she realized that the survey had missed several key geographical areas and included some that were outside the targeted region. Some survey questions were ambiguous; some respondents failed to answer all of the questions or gave silly replies. One manager said he worked 40 hours a day. Of the 1,000 surveys mailed only 80% were returned.a) What types of survey errors (lack of randomization, under-coverage, non-response, measurement errors, and so forth) were committed?b) What alternatives are available to the statistician?c) If you were the consultant, how might you respond to the supplier?When doing business research, it is important that you can identify critical factors that influence the research situation. Read the following case and answer the questions:A recent study by the Agency for Health Care Research Quality showed that adolescents who watched more than 4 hours of TV per day were more than five times as likely to start smoking as those who watched less than 2 hours a day.

Paid television tobacco ads are illegal). List, in rank order, six factors you think cause adolescents to start smoking. Did the TV portrayals of attractive smokers appear on your list? (Data is from the AHRQ Newsletter, no 269, January 2003, p.12) What are your thoughts on the result of the study?Recently, several studies have sought to measure the extent of binge drinking among college students.
