- Make five graphs of
**api99**: histogram, kdensity plot, boxplot, symmetry plot and normal quantile plot. - What is the correlation between
**api99**and**meals**? - Regress
**api99**on**meals**. What does the output tell you? - Create and list the fitted (predicted) values.
- Graph
**meals**and**api99**with and without the regression line. - Look at the correlations among the variables
**api99****meals****ell****avg_ed**using the**corr**and**pwcorr**commands. Explain how these commands are different. Make a scatterplot matrix for these variables and relate the correlation results to the scatterplot matrix. - Perform a regression predicting
**api99**from**meals**and. Interpret the output.
