Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.
Consider the following Box plots where data set A and data set B. Which data set has the largest variation?
SHOW ALL WORK, as modeled in class. For problems 1-4 calculate the following: a) Sort the data in ascending (increasing) order. b) Use the sorted data above to find the range of the data set. c) Give the Five-Number Summary. d) Check for outliers. Calculate left fence and right fence, and graph them as vertical dashed lines on your box plot. e) Construct a box (and whiskers) plot, using the five-number summary. f) If there are outliers, make a Modified Box Plot. g) Compute the mean, mode and standard deviation for the data set. Since all the data values below are whole numbers, round Measures of Center & Variation to one decimal place. 4.
