A college professor teaching a introductory psychology courses is interested in testing the effectiveness of a new online textbook in helping students learn course material. To test this, she assigns the new online textbook for her course and randomly selects a sample of her students (N=50) to complete a standardized general psychology exam at the end of the semester and finds a mean of M=75. The standardized exam has a mean of 73 with a standard deviation of 13 (population values). Did the online textbook have a significant effect on learning course material?
Complete the six steps of hypothesis testing using the format presented in class. Label all steps. Assume alpha level = .05
You may use the Math Editor in the toolbar of your answer space (fx) for formulas or you may use the Symbol tool (©) for math symbols and Greek letters. [Note: You may need to expand your toolbar with the Chevron symbol in the upper right corner of the answer space.] You may also copy and paste the following symbols if preferred:
