The cost of controlling emissions at a firm rises rapidly as the amount of emissions reduced increases. here is a possible model:
c(q) = 1,300 + 197q2
where q is the reduction in emissions (in pounds of pollutant per day) and c is the daily cost to the firm (in dollars) of this reduction. what level of reduction corresponds to the lowest average cost per pound of pollutant? (round your answer to two decimal places.)
a) pounds of pollutant per day
what would be the resulting average cost to the nearest dollar?
per pound

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
