A university wants to start a hockey team finding that 83% of a random sample of 100 people support the establishment of said team. However, the sample appears to contain 80 mean and 20 women; another random sample of the university body suggests that the true percentage of support for a hockey team is 55%. Calculate the test statistic one would use to determine if there is a significant difference between the male dominated sample and the "normal" sample.

Solutions

Expert Solution

Let p denotes the true proportion of people support the establishment of said team in the male dominated sample.

There is sufficient evidence to conclude that there is a significant difference between the male dominated sample and the "normal" sample.
