We have created a scientific experiment where one class of 40 people were taught using a flipped classroom. This class had an average score of 85. Also, we have observed from similar classes that σ = 3. We would like to test whether or not a flipped classroom improves the average grade compared to the standard class room’s mean grade of 84 with a standard deviation of 4. No students were in both the standard and flipped classrooms.

9. What is the population and sample for this problem?

10. What is the null and alternate hypothesis here?

11. Perform an α = 0.05 hypothesis test you have specified above. (Hint: 0.05 is the cutoff) [Indicate what the p-value is and whether or not you reject or fail to reject the null]

12. Perform an α = 0.01 hypothesis test you have specified above. (Hint: 0.01 is the cutoff)[Indicate what the p-value is and whether or not you reject or fail to reject the null]

Two sections of a class in statistics were taught by two different methods. Students’ scores on a standardized test are shown in Table 5.12 . Do the results present evidence of a difference in the effectiveness of the two methods? (Use α = 0.05.) Class A: 74, 97, 79, 88, 78, 93, 76, 75, 82, 86, 100, 94 Class B: 78, 92, 94, 78, 71, 85, 70, 79, 76, 93, 82, 69, 84 Include R code.
