Illustrative Example 1: A teacher from Mabuti Senior High School developed an Online Problem Solving Test to assess the effectivity of using online platforms in problem-solving ability of the students. 50 randomly senior high school students need to be selected. In this sample, x= 78 and s = 12. The mean µ and the standard deviation of the population used in the standardization of the test were 75 and 15, respectively. Use the 95% confidence level to illustrate the rejection region. Solution: 3. Determine the The problem does not specify the direction to which the hypothesis will be leading. It means that the test is eritical value fone-tailed) or Two-Tailed Non-directional. values (two Confidence Level 98% Critical Values: - +1. 96 Steps llustration tailed). 1.
