μ μ μ 1 The Critical-Value Approach to Hypothesis Testing Recall that for the p-value approach to hypothesis testing we: 1. Stated the null and alternative hypotheses 2. Calculated the probability of observing a sample statistic as contrary to the null hypothesis as what we did observe from our sample data. (If the hypothesis test was one-tailed, the calculated probability was our reported “p-value”. If the hypothesis test was two-tailed, we doubled our calculated probability and reported that for our p-value). 3. We compared our p-value to our level of significance for testing ( α ). If our p-value was less than , we rejected the null hypothesis. α Otherwise, we could not reject the null hypothesis. In the critical value approach to hypothesis testing we do the following: 1. State the null and alternative hypotheses 2. Select the level of significance 3. Select the “critical value” of the test statistic 4.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
