A survey by Accenture indicated that 64% of millennials as compared to 28% of baby boomers prefer “hybrid� investment advice-a combination of traditional advisory services and low-cost digital tools-over either a dedicated human advisor or conventional robo-advisory services (computer-generated advice and services without human advisors) alone.
Suppose that the survey was based on 500 respondents from each of the two generation groups.
a. Construct a contingency table.
b. Give an example of a simple event and a joint event.
c. What is the probability that a randomly selected respondent prefers hybrid investment advice?
d. What is the probability that a randomly selected respondent prefers hybrid investment advice and is a baby boomer?
e. Are the events “generation group� and “prefer hybrid investment advice� independent? Explain?

- According to the American Management Association, most U.S. companies now test at least some employees and job applicants for drug use. The U.S. National Institute on Drug Abuse claims that about 15% of people in the 18-25 age bracket use illegal drugs. Allyn Clark, a 21 year-old college graduate, applied for a job at the Acton Paper Company, took a drug test, and was not offered a job. He suspected that he might have failed the drug test, even though he does not use drugs. In checking with the company's personnel department, he found that the drug test has 99% sensitivity, which means that only 1% of drug users incorrectly test negative. Also, the test has 98% specificity, meaning that only 2% of nonusers are incorrectly identified as drug users. Allyn felt relieved by these figures because he believed that they reflected a very reliable test that usually provides good results. But is this really true? The accompanying table shows data for Allyn and 1,499 other job applicants.

He proposed tax reductions as a means of stimulating the economy and, as a result, increase tax revenues. In the mid 1990’s Time magazine reported that 30% of the US Congress supported a tax cut as a means of stimulating the economy and increasing tax revenues. Suppose at that time 5 members of congress were randomly selected for an interview and asked whether they supported a tax cut to stimulate the economy. 1.2) Find the probability that at least three of the five members of congress who were interviewed were in favour of a tax cut (rounded off to four decimals).arrow_forward
