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)
