The SAT subject tests in chemistry and physics for two groups of 15 students each electing to take these tests are given below.

To use the two-sample t-test with a pooled estimate of Ïƒ2, you must assume that the two population variances are equal. Test this assumption using the F-test for equality of variances. What is the approximate p-value for the test?

Chemistry -= 644 s = 114 Physics x = 658 s= 103 = 15
