b) Conduct t-test analysis, using guidelinesbelow

c) Write your results in a report, using theoutline given below

5. Turn in your written report using the linkin Module 9 of the course Blackboard site.

Data Collection Options: The following aresuggestions on where you can collect data.

This includesconducting surveys.

Project Design

There are 3 project design options for thet-test project, listed below. To see components and examples for each type ofproject design, consult the t-test Project Examples Word document or the t-testProject Resources PowerPoint file.

A. The 1-sample t-test (Sample size must beat least n = 40.)

B. The matched pairs t-test (Sample size mustbe at least n = 40.)

C. The 2-sample t-test (independent samples)(Sample size must be at least n = 50. You may split this across your twosamples; for example, you may have two independent samples of size 25, or oneof 27 and another of 23, etc. Although your independent samples are notrequired to be identical in size, it is better if the sample sizes aresimilar.)
