Two groups of students are tested after two types of instruction. Student Group 1 receives traditional instruction and Student Group 2 receives modified instruction. Below are the t-test results: t-Test: Two-Sample Assuming Equal Variances Students 1 Students 2 Mean 15.3 16.9 Variance 4.9 2.766666667 Observations 10 10 Pooled Variance 3.833333333 Hypothesized Mean Difference 0 df 18 t Stat -2.82732877 P(T 0.042139087 t Critical one-tail 1.734063607 P(T 0.034278174 t Critical two-tail 2.10092204 What is the null hypothesis? Use the two-tail probability. Is there a difference between the group of students in group 1 and students in group 2? In a sentence or two, describe the results in terms of the statistics as you would for an academic article.
