Unformatted text preview: samples t-test to determine if there is a statistically significant difference between student performance in the two sections. Use the 5-step framework. Make sure to write the hypotheses and conclusion in terms of the problem above. 3. Calculate whether p < .05 for the difference in means for the following samples. Assume a 2-tailed test. You do not need to write out hypotheses or conclusions. (This problem requires calculating t for unequal sample sizes, which will be covered Tuesdays class/reading.) Sample 1: mean = 20, standard deviation = 5, N = 12 Sample 2: mean = 16, standard deviation = 3, N = 24...
