Next, let's calculate the t-statistic for the pooled two-sample t-test. Below are the summary statistics for children who smoked and children who did not smoke: Sample Size Sample Mean Sample Standard Deviation Smoking children 65 3.2768 0.7500 Non-smoking children 589 2.5661 0.8505 1. Calculate sp, the pooled sample standard deviation. Report your answer to four decimal places. 2. Using the correct answer to question #1, calculate SE(X smoking nonsmoking). Round your answer to five decimal places. 3. Calculate the difference in sample means (Tsmoking - nonsmoking). Report your answer to four decimal places. 5. The degrees of freedom for the t-statistic in the above question = 4. Using correct answers from above, calculate the t-statistic. Report the t-statistic to four decimal places.
