Please SHOW THE 7 STEPS IN TESTING THE HYPOTHESIS I. HoII. Alpha = ?III. T-test? F-test?IV. Sig Value = ?V. t-value = ?VI. DECISION: Qestion: To compare freshmen’s knowledge of mathematics in two departments of a university, a certain professor in Mathematics got a sample of Education and Nursing students and gave a special examination. A sample of 25 Education students has a mean score of 88.50 with standard deviation of 7.5. A sample of 29 Nursing students have a mean score of 90.25 with a standard deviation of 8.2. Is there a significant difference between the two sample means? Use = .01 level of significance.
