Unformatted text preview: samples ttest to determine if there is a statistically significant difference between student performance in the two sections. Use the 5step 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 2tailed 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...
