The following are heat producing of coal capacities fro two mines( in millions of calories per tonne)
Mine A: 8500, 8330, 8480, 7960, 8030
Mine B: 7710, 7890, 7920, 8270, 7860

Assume that the data constitute independent random samples from normal distributions with equal variances. Test at the 0.01 level of significance whether the means of the heat-producing capacities of coal from two mines is different.

Suppose there are two firms producing coal. Coal sells at a constant price p = $60/ton. Each firm, i, has private marginal cost PMCi = 5 + 1.1qi, where qi is the quantity of coal firm i produces in tons, and the units of PMCi are $/ton. Each ton of coal produced creates 10 lbs of SO2 pollution. Suppose there is a cap-and-trade system for SO2 emissions in this coal industry. If the regulator sets the cap at 800 lbs...
