Partial Question 8 4 / 5 pts A professor is concerned that the two sections of college algebra that he teaches are not performing at the same level. To test his claim, he looks at the mean exam score for a random sample of students from each of his classes. In Class 1, the mean exam score for 12 students is 78.7 with a standard deviation of 6.5. In Class 2, the mean exam score for 15 students is 81.1 with a standard deviation of 7.4. Test the professors' claim at the 0.05 level of significance. Assume that the population standard deviations are equal. Ho: m1 - m2 = 0 Ha: . m1 - m2 0 t-Test Statistic (round to three decimal places) = -0.883 Critical t-score (to or ta/2, they should be positive, use the t-distribution table) = 2.059 Conclusion (write "R" for reject Ho, and "F" for fail to reject Ho): F
