Full Hypothesis Test Examples · Exercise 32
A statistics instructor believes that fewer than 20% of Evergreen Valley College (EVC) students attended the opening night midnight showing of the latest Marvel Universe movie. The instructor surveys 84 students and finds that 11 of them attended the midnight showing.
At a 1% level of significance, an appropriate conclusion is:
(a) There is insufficient evidence to conclude that the percent of EVC students who attended the midnight showing of a Marvel Universe movie is less than 20%.
(b) There is sufficient evidence to conclude that the percent of EVC students who attended the midnight showing of a Marvel Universe movie is more than 20%.
(c) There is sufficient evidence to conclude that the percent of EVC students who attended the midnight showing of a Marvel Universe movie is less than 20%.
(d) There is insufficient evidence to conclude that the percent of EVC students who attended the midnight showing of a Marvel Universe movie is at least 20%.
