The average final exam score for the statistics course is 76%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is lower. The final exam score for the 13 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 76, 54, 57, 83, 52, 86, 79, 64, 53, 53, 68, 75, 57 What can be concluded at the the a = 0.10 level of significance level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: pv Select an answer♥ Hị: ?v Select an answer♥ c.

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.
