Venturi scrubbers remove submicron particles found in waste gas streams, an experiment was conducted at a manufacturing site measuring the performance of the scrubber at various airflow rates (cubic meters per minute). The performance is measured in NTU’s: transfer units of mass (or heat) higher values indicate better performance. Given the data below, construct the residuals plot.

Engine oil purifier machines can effectively remove acid, pitch, particles, water, and gas from used oil. Purifier A was purchased 5 years ago for $90,000. Its operating cost is higher than expected, so if it is not replaced now, it will likely be used for only 3 more years. Its operating cost this year will be $140,000, increasing by $2000 per year through the end of its useful life, at which time it will be donated for its recyclable scrap...

An experiment was conducted to determine the concentration of a particular bacterium (Pseudomonas syringae) found adhering to rocks in river beds. Of particular interest was whether the number of bacteria was the same for rocks near the source of the river versus rocks near the outlet of the river. The experiment was conducted as follows. Six rivers in Iowa were randomly sampled. Then, for each river, the number of bacteria was measured for rocks at the source of the river...
