You toss a coin 80 times and get many more heads than expected. With a computer, you determine that the probability for this, or even more heads out of 80, the happening was only 0.4% if the coin was a fair coin. Your null hypothesis is that the coin was fair. Among the given options, what is the lowest significance level at which you can reject the null hypothesis? a. 0.01% b. 10% c. 1% d. 5% e. 0.1%

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.
