The two-sample t-test is applied to compare whether the average difference between two groups is significant or if it is due instead to random chance.

Use good references,

1. Briefly, describe the difference between Unpaired Two-Sample T-test and Paired Two-Sample T-test.

2. Provide an application example for Unpaired Two-Sample T-test, and stablish the Ho and Ha Hypotheses.

3. Provide an application example for Paired Two-Sample T-test, and stablish the Ho and Ha Hypotheses.

4. Explain the purpose of P-values and its application in the context of your two examples.

A t-test is used to compare the means of one variable for two groups of cases. As an example, a practical application would be to find out the effect of a new drug on blood pressure. Patients with high blood pressure are randomly assigned into two groups, a placebo group and a treatment group. The placebo group would receive conventional treatment while the treatment group would receive a new drug that is expected to lower blood pressure. After treatment for...

The Independent Samples t Test can only compare the means for two (and only two) groups. It cannot make comparisons among more than two groups. If you wish to compare the means across more than two groups, you will likely want to run an ANOVA. What is the main differences between an unpaired and paired t-test? Why would you want to limit the number of variables you are comparing? Why would you want to start with two groups and work...
