T-test for two samples
A drug company is measuring levels of oxygenation in patients after receiving a test medication. As the researcher, you are interested in whether Group I, which received the medication, has the same oxygenation levels as Group II, which did not.
1) Group 1: 2, 3, 3, 4, 4, 7, 8, 9
2) Group 2: 1, 2, 2, 3, 4, 4, 5, 5, 6, 8
Use Excel to run a t-test for two samples, assuming equal variances, with an alpha value of 0.05. Run the t-test and note:
1) Are you doing a one-tailed test or a two-tailed test (Excel will give you both)?
2) What is the probability that Group I is different from Group 2, using the p value? Is it significant against the benchmark of p < .05?
APA format is not required, but solid academic writing is expected.
