Sample B Sample A 0 50 100 150 Income (in thousands) 3) 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. 4) The mean of sample B is 20.745 thousand dollars and the median is 0 thousand dollars. Why is there such a large difference in these values? Which value would be better to report as the center of the distribution of the twenty salaries? 5) Here are some statistics about the salaries from Sample A. Mean = 27.195 thousand dollars Q1 = 8.5 thousand dollars Q3 = 38.5 thousand dollars Standard deviation = 23.2 thousand dollars Based on these statistics, write a sentence to interpret the IQR in context and write a second sentence to interpret the standard deviation in context.
