True or False The PEW Researcher center based on a sample of 10,000 recent college graduates says the average amount of money owed in student loans is $31,800. The value of $31,800 is a statistic. A study is observational when the researcher controls the behaviors of their subjects.
CURSED MOVIE Released in 1956, the movie The Conqueror attracted considerable attention because many members of the cast and crew died from cancer supposedly resulting from exposure to radioactive fallout. The movie was shot a short distance from a site in Nevada where above-ground tests of atomic weapons were conducted. Among the 220 cast and crew members, 91 developed cancer. According to the National Cancer Institute, for that time period and for the age cohort, the incidence of cancer was about 40%. Use a 0.05 significance level to test the claim that the sample of cast and crew members is from a population in which the rate of cancer is greater than 40%. What do you conclude about the movie being a curse? Find null hypothesis and alternative hypothesis. Find test statsistic. Find P-value. How do you find p hat

HOW Do I solve this in EXCEL In 2016, the Better Business Bureau (BBB) settled 80% of complaints they received in the US. Suppose you have been hired by the BBB to investigate the complains they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the BBB is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.8, the same as the overall proportion of complaints settled in 2016. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of pbar. Based on a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion? Suppose you select a sample of 450 complaints involving new car dealers. Show the sampling distribution of pbar. Based on the smaller sample of only 450 complaints, what is the probability that the sample proportion will be within…
