A small group of IVC students took a math test and then got an opportunity to retake the math test. They went to get tutoring in between the two attempts. The table below shows the scores of 10 IVC students before and after tutoring Is there compelling statistical evidence that the tutoring is effective in improving scores? Use a significance level of 0.05. We have the differences (gain or loss), but we still need to compute the mean, standard deviation, and know the sample size for the differences (use Excel or Sheets for this computation). Once those are found, we can apply methods that are used for a sample t-test Student Before Tutoring Alar Tutoring Difference 1 71 75 2 79 70 65 4 13 56 67 3 3 4 5 8 10 6 75 78 78 ? 8 9 10 B5 85 33 95 B2 80 8.33 5 8 20 24 62 56 Null Hypothesis, HO Alternative Hypothesis, H1 Test Statistic, P-value Significance level
