Good day everyone. So here for our solution we have our standard error that would be equal to 35

Hello students in the first question, we have given the standard deviation of the population tha

we are asked in order to calculate null hypothesis and alternative hypothesis okay so basically

So we will be assuming that we're using an alpha level of .005 and our differences, I have subtr

Hi in this question we want to test a minor hypothesis we say that the mean is equal to 34 again

Question

Use the traditional or classical 8-Step Approach for hypothesis testing and the formulas from chapter to justify your answer for the following questions. Be sure to state conclusions written in paragraph form for the hypothesis testing where appropriate. A follow-up sentence may be needed in your conclusion as well. #5) A researcher is testing the effectiveness of two different methods of teaching Chemistry. Method 1 uses a Lecture-based approach and Method 2 uses an Internet-based approach. The resulting statistics for the scores on the comprehensive final test are shown in the table below: Method 1 (Lecture-based Approach): n1 = 29, X1 = 81.2, S1 = 7. Method 2 (Internet-based Approach): n2 = 24, X2 = 76.7, S2 = 6.3. Assume samples were taken from independent and normally distributed populations where Ïƒ1 and Ïƒ2 are unknown and not assumed equal. Test the claim that the mean scores on the comprehensive final test are equal for the groups taught by Method 1 versus Method 2. Use Î± = 0.05.
