It is known that 75% of undergraduates at one school say they will get a covid vaccine as soon as they are able to. You wish to test if the proportion of students who say they will get a covid vaccine as soon as they are able to differs from 75%. Set up hypotheses and perform the test based on results from a poll we will hold in class this week. Use a significance level of α = .01. Given: Poll results: 51 (89%) of students will get a covid vaccine, and 6 (11%) will not get. Total 57 students on a poll.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
