Suppose you were trying to determine if there was a difference in the means of 4 different groups, and instead of using an ANOVÀ test, you decided to carry out 6 separate 2-sample t-tests to compare every possible combination of groups and you set the Type I error rate as a = 0.05on all of those tests. Use this information and calculate the familywise Type I error rate for this scenario. Make sure to round your answer to 3 decimal places. For example, if you thought the answer was 0.12345 then you would type in 0.123.

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.
