Write a program in R that fits and interprets a regression model to the smiles.csv data. Your program should do the following (though not necessarily in order):
1. Produce a boxplot of leniency score for the various types of smiles
2. Fit the regression model that treats "neutral" as the reference level of type and perform a test of the equality of the means of the levels of type
3. Estimate the population-level mean leniency score for the levels of type with their standard errors
4. Estimate all differences in population-level mean leniency scores for the levels of type with their standard errors
5. Produce an effects plot of the effect of the levels of type on leniency score
