Question

From previous studies, it is concluded that 80% of workers indicate that they are satisfied with their job. A researcher claims that the proportion is significantly different than 80% and decides to survey 300 working adults. Test the researcher's claim at the

α=0.02 significance level.

Answer 1

To test the researcher's claim, we need to conduct a hypothesis test. The null hypothesis, denoted as H0, is that the proportion of workers who are satisfied with their job is equal to 80%, and the alternative hypothesis, denoted as Ha, is that the proportion is significantly different than 80%.

To conduct the hypothesis test, we first need to calculate the sample proportion of workers who are satisfied with their job. To do this, we need to know how many of the 300 workers surveyed indicate that they are satisfied with their job. Without this information, it is not possible to conduct the hypothesis test.
