How to fill out t-test and hypoformsis testing

1. Identify the null hypothesis (H0) and alternative hypothesis (H1) for the test.
2. Collect the data and calculate the sample means, standard deviations, and sample sizes for each group being compared.
3. Calculate the t-statistic using the formula t = (mean1 - mean2) / (sqrt((s1^2/n1) + (s2^2/n2))), where mean1 and mean2 are the sample means, s1 and s2 are the standard deviations, and n1 and n2 are the sample sizes.
4. Determine the degrees of freedom for the test, which is equal to (n1 + n2 - 2) where n1 and n2 are the sample sizes.
5. Use a t-distribution table or statistical software to find the critical t-value for the desired level of significance and degrees of freedom.
6. Compare the calculated t-value to the critical t-value to determine if the null hypothesis should be rejected.
7. Make a decision about the null hypothesis based on the comparison and report the results.
