In 2016, the US Department of Agriculture established a “maximum acceptable” salmonella
prevalence of 15.4 percent for chicken parts sampled at the end of a slaughterhouse’s kill line. 54 of the
154 largest chicken-slaughter facilities in the US failed to meet this standard in 2018. Assume that these
results are representative for all large chicken-slaughter facilities. Suppose that in a random sample of 60
chicken parts from the large ACME chicken-slaughter facility (which produces 1,000,000 chicken parts
per year), 45 chicken parts test negative for salmonella.
a) Report a point estimate for the prevalence of failing to meet the chicken part salmonella standard
among large chicken-slaughter facilities, and test the null hypothesis that this prevalence is 20%.

Smith obtained data on a sample of 220 trees, and in that sample, the mean production of fruit was 6.33 bushels, with a standard deviation of 2.81. Using a significance level of .01, test the claims. Show any notation used for the...

1. The US Department of Education was established as a new cabinet department in 1982. College costs (tuition, room, board, books, expenses), after adjustment for inflation, have gone up from $8,000 in 1980 to more than $20,000 today. Is this a coincidence? Discuss how the government may be helping colleges raise total costs through collusive behavior and first-degree price discrimination. 2. Drug firms engage in third-degree price discrimination when they sell their products overseas for a lower price than in...
