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
No written by hand solution The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States were 459 eight-ounce servings (Coca-Cola Company website, February 25, 2017). Suppose you are curious whether the consumption of CocaCola beverages is higher in Atlanta, Georgia, the location of Coca-Cola’s corporate headquarters. A sample of 61 individuals from the Atlanta area showed a sample mean annual consumption of 479.5 eight-ounce servings with a standard deviation of s = 90 ounces. Using α = .01, does the sample support the conclusion that means annual consumption of Coca-Cola beverage products is higher in Atlanta? Use both the critical value and p-value approach to test the hypothesis that H0: µ >459 in Atlanta vs. the 1-sided alternative. 7.
