A research team wants to compare the effectiveness of two different teaching methods on student test scores. They conduct a study with two groups of students. Group A receives Teaching Method A, and Group B receives Teaching Method B. The test scores of the students after the teaching intervention are recorded. The data for Group A is as follows:

85, 88, 82, 90, 78, 86, 92, 80, 85, 81

And the data for Group B is as follows:

92, 88, 86, 84, 90, 91, 87, 85, 88, 89

Using Microsoft Excel, conduct a two-sample t-test to determine if there is a significant difference in the average test scores between the two groups. Use a significance level of 0.05.
