I just received an email from the other professors: in order to stay coordinated with the other sections, Midterm 2 will be given *tonight* rather than one week from now. As a reminder, the topics for the midterm are: * Statistical inference for one percentage: confidence intervals, hypothesis tests, sample size * Statistical inference for one average: confidence intervals, hypothesis tests, sample size * Statistical inference for two percentages: confidence intervals, hypothesis tests * Statistical inference for two averages: confidence intervals, hypothesis tests * Statistical inference for multiple percentages (chi-square test of independence) * Statistical inference for matching theoretical distributions (chi-square goodness of fit test) * Statistical inference for multiple averages (ANOVA F test) * Regression for description: interpreting correlation, R^2 * Regression line: OLS criterion, formula and interpretation of slope, formula and interpretation of Y-intercept, formula and interpretation of s * Regression for inference: assumptions of the simple regression model, inference for slope, predicting individual Y at X, predicting average Y at X * Reading computer output (Excel, Minitab) Good luck on the midterm tonight! Oh, and one other topic: * the importance of not believing every post made on this day (check calendar if you are not sure)
