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.
