Group of answer choicesSuppose that 19% of all athletes in a sport use a banned drug. A test is available that detects 88% of athletes who use the drug. But the test also gives a positive result for 9% of those who do not use the drug. What percent of athletes who test positive for the drug are actually using the drug? Answer: %I need help with this problem I want to learn about. A recent year was randomly picked from 1985 to the present. In that year, there were 2,052 Hispanic students at a public university out of a total of 12,328 students. At a community college, there were 324 Hispanic students out of a total of 2,441 students. In general, do you think that the percent of Hispanic students at the two colleges is basically the same or different? (Use ? = 0.05.

Thank youCURSED 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 hatchexteen
