###### To compare freshmen's knowledge of history, samplesof 50 freshmen from each of twouniversities were given a special test. Those from the firstuniversity have an average scoreof 67.4 with a standard deviationof 5.0 while those from the seconduniversity have an average scoreof 64.8 with a standard deviationof 4.6. At the 0.02 level of significance,the hypotheses tested are H0:Âµ1 - Âµ2 = 0against H1: Âµ1 â€“Âµ2 â‰  0. Find the critical value.1.96 2.052.33 1.28

To compare freshmen's knowledge of history, samples of 50 freshmen from each of two universities were given a special test. Those from the first university have an average score of 67.4 with a standard deviation of 5.0 while those from the second university have an average score of 64.8 with a standard deviation of 4.6. At the 0.02 level of significance, the hypotheses tested are H0: Âµ1 - Âµ2 = 0 against H1: Âµ1 â€“ Âµ2 â‰  0. Find the critical value. 1.96 2.05 2.33 1.28
