Now, let's look at a situation in which we compare three college math teachers to each other with respect to how interested they keep their students. The study was conducted among freshmen enrolled in an introductory course. The unit was quadratic equations. Students were asked to jot down an x on a piece of paper every time they found their attention drifting away from the lecture. What test or tests would you use to rule out chance from causing the apparent differences in these data?

Here are data from one fifty minute lecture:

Teacher A	Teacher B	Teacher C
5	9	4
5	7	4
7	4	6
4	7	5
6	8	6
6	7	5
5	4	4
5	5	6
43	51	40

Select the correct statistical test; perform the test; report the results according to the handbook guidelines; explain what the results mean.

Please use excel single factor ANOVA and Tuckey Test , Also Write the Null Hypothesis and Alternate Hypothesis .
