In the test of hypothesis ?0:?=100 vs . ??:?>100, we already have the p-value for this test: P-value=0.0228. Which of the following (with the reason) will be correct with significance level at .05? Group of answer choices Reject ?0H0 since the P-value is greater than .01. Fail to reject ?0H0 since the P-value is greater than .01. The information is not enough to make a decision. Fail to reject ?0H0 since the P-value is less than the significance level. Reject ?0H0 since the P-value is less than the significance level.

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.
