Unformatted text preview: MATH 1131: ASSIGNMENT I SOLUTIONS/ANSWERS 1. The three different bar charts are given below. Vancouver Edmonton Saskatoon Winnipeg Toronto Montreal St.John Halifax geographic order 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 Halifax Toronto Montreal Vancouver Winnipeg Edmonton Saskatoon St.John Pareto chart 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 The Pareto chart (ordered by size) is more effective, and cleaner looking. You could also look at the chart with the bars ordered by population size... or any other interesting covariate you could think of. St.John Halifax Saskatoon Vancouver Winnipeg Edmonton Montreal Toronto ordered by population 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 2. The histogram is right-skewed, unimodal, and it looks like we have a couple of outliers. Frequency Histogram of Oil Produced amount produced (in thousands of barrels) Frequency 50 100 150 200 5 10 15 20 The mean is 48.25 and the median is 37.5, which matches the right-skew of the his- togram, since the mean is greater than the median. The five-number summary is 2 21.4togram, since the mean is greater than the median....
