**Building Notes of Destiny**For A Brighter Future**Problem #1**• Scripts for slope, intercept, and r2. • Notes on how to estimate, find residuals, interpret residuals, and problems with estimating.**Problem #2**• Parameter of Interest is the “value they are measuring, but extended to the whole population”.**Problem #3**• The z-score and reverse z-score formulas. • Notes on how to draw a picture. • A reminder about dividing by the square root of n. • Possibly instructions for using normalcdf and invNorm.**Problems 4 and 5**• The cheat sheet stuff. • Seriously. • Also notes on error types. • Also notes on how confidence level and sample size affect the interval and why.**Problem 6**• The cheat sheet stuff. • Seriously. • Also, maybe remember that if we find a difference (low p-value) it is statistically significant. • We use the confidence interval to discuss practical significance.**Problem 7**• CHIX generates matrix B, and editing matrix B is how you find the expected values. • The assumption checks are the expected value check and the random check.**Problem 8**• Know the formatting and usage of: • Binompdf • Binomcdf • Geometpdf • Geometcdf • When to subtract from 1
