An electric utilities company must choose between two technology options for generating electricity for its customers in the future: coal or nuclear energy. In order to assess the attitudes of local citizens, the power company conducted a public opinion poll. Four sectors were considered: news media, coal miners' union, environmentalists and conservationists, and local groups. Fifty (50) persons were randomly sampled from each sector and asked to give their opinions. The results of the survey are shown in the table below: Coal Environmentalists News Media Miner's and Local Groups Total Union Conservationists Support Coal 21 42 11 25 99 Option Support Nuclear 18 2 16 13 49 Option Neutral 11 6 23 12 52 Totals 50 50 50 50 200 Can we safely assume with 90% confidence that opinion regarding the choice of future technology options for generating electricity is independent of the type of public sector? What is the critical chi-square value for this test?

California insurance companies wanted to study factors (e.g., the proximity to a major earthquake fault line) that may influence homeowners’ decisions to purchase earthquake insurance. Surveys were mailed to randomly selected households in three California counties to investigate the possible proximity effect. The data collected are shown below: Los Angeles San Bernardino Santa Clara sample size 1,000 1,400 1,200 Number with 377 469 390 earthquake insurance Los Angeles County is located closest among the three to a major earthquake fault line. Are homeowners in Los Angeles County more likely to purchase earthquake insurance than those in San Bernardino County? Test using α = 0.05. (Optional) Are homeowners in Los Angeles County more likely to purchase earthquake insurance than those in Santa Clara County? Use α = 0.05.

At an assembly plant, workers assemble parts for a piece of farm equipment. The supervisor conducted an experiment to compare the effectiveness of three assembly methods, A, B, and C. Eighteen employees were randomly assigned, six employees each, to one of the three methods. After completing their training, each person was asked to assemble five pieces of equipment using his or her training method. The average time to complete the assembly of all five pieces of equipment was recorded. (a) What type of study design is used? O independent groups design O repeated measures design O matched pairs design O randomized block design What are the experimental units in this study?
