Ok here is the entire assignment
Module 5 Application
Submit at the end of Module 5.
Overview: Calculating t-tests for Independent and Dependent Samples
In this Application assignment, you will conduct an independent, two-tailed test and a dependent, two-tailed test on a data set. You will use the seven-step process in conducting the two tests.
Directions
- Review the video, t-tests in Microsoft Excel, in the multimedia presentations to understand the applications for both independent and dependent t-test measures using an Excel program.
- Use the data sheet and enter data from 1-15 as Group A for the variable height and from 16-30 as Group B for the variable height in an Excel program.
- Assuming equal variances, conduct a two-tailed, independent t-test on the data.
- Next, conduct a two-tailed, dependent t-test on the data (no need to assume equality of variance in a dependent t-test).
- Complete the seven-step process for each of the t-tests in this documents. Retain the yellow highlights for the answers. (In the Tables packet you downloaded, you will use Table 3 - Percentage Points of Student's t Distribution to determine appropriate critical value).
Part 1: Seven-Step Process for the Two-Tailed Test of Independent Samples
Step 1:Set your hypothesis.
Ho:(in statistical form)
Ha:(in statistical form)
Step 2:Determine testing Alpha Level - Alpha level = ___
Step 3:Sampling distribution = t?
Step 4:Decision RuleI will reject the Ho if my tobs value falls at or beyond my tcrit value of ______; otherwise, I will fail to reject.
Step 5:Calculate P-value in excel P-value = ______
Step 6:Since my P-value of ______ is (< or >--choose symbol) than my chosen Alpha Level of _____, I, therefore, reject or fail to reject (choose one) the null hypothesis.
Step 7:Since I rejected or failed to reject (choose one) the null hypothesis, I, therefore, conclude (fill in the conclusion based on your decision in step 6).
Part 2: Seven-Step Process for the Two-Tailed Test of Dependent Samples
Step 1:Set your hypothesis.
Ho:(in statistical form)
Ha:(in statistical form)
Step 2:Determine testing Alpha Level - Alpha level = ___
Step 3:Sampling distribution = t?
Step 4:Decision RuleI will reject the Ho if my tobs value falls at or beyond my tcrit value of ______; otherwise, I will fail to reject.
Step 5:Calculate P-value in excel P-value = ______
Step 6:Since my P-value of ______ is (< or >--choose symbol) than my chosen Alpha Level of _____, I, therefore, reject or fail to reject (choose one) the null hypothesis
Step 7: Since I rejected or failed to reject (choose one) the null hypothesis, I, therefore, conclude (fill in the conclusion based on your decision in step 6).
