(True data) According to historical records, from 1891 through 2011, total snowfall per season in the Twin Cities averaged 46.6 inches with a standard deviation of 18.5 inches. If these averages hold for future years (a questionable assumption given climate change), what is the probability that the mean snowfall for a random sample of nine seasons will be greater than 50 inches?

The latest poll results by a reputable organization show that 16% of adult Americans hold that the government, media, and financial worlds are controlled by Satan-worshipping pedophiles. In a random sample of 20 adult Americans, what is the expected value (the "expected" number) of adults who believe the Satan-worshipping conspiracy? (2) 26.

A study from the University of Texas Southwestern Medical examined people being treated for non-blood- related diseases to see whether the risk of hepatitis C was related to whether people had tattoos and to where they got their tattoos. Hepatitis C causes about 10,000 deaths each year in the US. For purposes of this problem, assume that the results shown in the table represent the entire population of interest.
