A high school teacher is interested to compare the average time for students to complete a standardized test for three different classes of students.

The teacher collects random data for time to complete the standardized test (in minutes) for students in three different classes and the dataset is provided below.

The teacher is interested to know if the average time to complete the standardized test is statistically the same for three classes of students. Use a significance level of 5%.

The teacher has confirmed that the samples were randomly selected and independent, and the populations have normal distribution and the population variances are equal.

(a) calculate the Test Statistic for this example (round your answer to 2 decimal places)

(b) calculate the P-value for this example (round your answer to 2 decimal places)

"Class A" Class B Class C 111 120 107 75 96 93 109 112 89 101 89 117 102 103 82 81 112 64 103 98 107 87 101 101 88 82 114 83 79 111 81 91 88 91 102 102 92 103 94 90 95 84 93 104 113 90 97 98 79 83 104 93 91 106 77 104 85 98 95 103 83 100 98 98 94 88 88 107 107 101 103 106 86 97 91
