This Case Study will allow you to demonstrate your knowledge of Means (A/B) Testing and Variance Testing. Before we get into that, however, I have some detailed videos that show you the concepts behind each. In addition, I have also provided videos that show you how to do each test. Click the Khan Academy (Links to an external site.) link to find learn more about means testing and the math behind it. Click the YouTube link to find a video where I demonstrate how to do Mean and Variance Testing in Excelhttps://youtu.be/JbNAljeFy4EREALNow that you know how to conduct a test for variances and means, use that knowledge to complete the following Case Study. Seacoast Bank wants to find out how much time (in seconds) it takes to complete transactions for each of three methods. So they clocked the procedures and averaged them over the last month. The results are to the left. Of course, we know that the lower the time, the faster the method.Your tasks...Formulate and test the hypotheses to determine if the variances are different.Formulate and test the hypotheses to determine if the means are different.Note: You will conduct three separate tests for F tests and three for t tests.test 1: Face to Face vs ATMtest 2: Face to Face vs Onlinetest 3: ATM vs Online3. Write a report detailing your hypotheses, the test procedures you did, and the results.

This week, we talked a lot about children's experiences in school and different approaches to student learning. Reflect on your experiences as an elementary school student. How would you rate the quality of teachers in your elementary school? Provide a description of your favorite elementary school teacher. In particular, talk about whether your favorite teacher used direct instruction, a constructivist approach, or some combination of both. Please be specific and give examples. How did your teacher's approaches impact your academic development?
