2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:

7. Many businesses have music piped into the work areas to improve the environment. At a company an experiment is performed to compare different types of music. Three types of music - country, rock, and classical – are tried, each on four randomly selected days. Each day the productivity, measured by the number of items produced, is recorded. The results appear below: Country Rock Classical 857 791 824 801 753 847 795 781 881 842 776 865 1.1. Is there a significant difference between the three types of music? Use a =.05. 7.2 Solve using Analysis of Variance. 7.3 Which type of music seem to be best? 7.4 Which type of music seem to be worst?
