18. A group of Industrial Organizational psychologists wanted to test if giving a motivational speech at the end of a meeting would encourage office workers to have a higher output to their work based on the numbers of sales each workers made. The group tested 10 participants that were in two conditions where one meeting ended in a motivational speech and another were no motivational speech was given. Here are the number of sales that was produced by the 10 participants for both conditions:
Yes speech: 2, 6, 1, 9, 3, 12, 8, 0, 5, 1
No speech: 3, 0, 5, 10, 1, 8, 2, 1, 9, 11
Use the four steps of hypothesis testing to find out if there is a
significant difference between the two groups, using APA format to
answer the question.
20. Run the same data from question 19 (and the same criteria)
using a repeated measures t test.
a. Perform the test and report results (show ALL work)
b. Explain what the difference in results is due to.

Let ππ represent the percentage of all male students who would
receive a grade of C on this test. Use a 80% confidence interval to
estimate p to three decimal places.
Enter your answer as a tri-linear inequality using decimals (not
