c. Run a two-sample paired t-test for means to test your hypothesis, using a confidence level of 95%. To show whether it is a one-tail test or a two-tail test, highlight the significant values in the Excel output, including your p-value, critical t, and t stat. and write a sentence or two to interpret the results. should the null hypothesis be rejected?

I think this question should use t-Test: paired two sample for means, but my friend think it should use t-test: t-test: Two-sample assuming equal variances. So, I need someone to help me explain which method is correct and answer the following question. Thanks!!

Look at the table for the Paired samples test to find your t
calculated, df, and significance. Remember that significance level
will appear in the Sig (2-tailed) column. Any value that is smaller
than .05 will be significant at the .05 level or higher. In a
sentence describe the results and report them in APA style,
including r2 and evaluation (you will need to calculate
r2 by hand).

Design your own study using one of the following statistical tests: one-sample t-test, paired samples t-test, independent samples t-test, or ANOVA. Give (1) your sample, (2) research question, (3) the appropriate test with the null and research hypotheses, and (4) the two variables, including (a) how you would measure both variables and (b) each variable’s level of measurement. Be creative. Do not include data in your response.
