The American Community Survey is administered by the US Census Bureau annually. Two different random samples of size n=20 from the data for the year 2017 were selected. One of the variables of interest in the data set was annual salary (in thousands). A boxplot was created for each sample of 20 . Describe the similarities and the differences in the boxplots. Be sure to discuss skewness, variability, center, quartiles and outliers.
