Suppose a major oil company hired a survey organization to conduct a study of citizens living with 5 mi of the coast. The survey question is, "Do you want to save money at the gas pump? Well then you would be in favor of off shore drilling right?"

Explain the bias that exist in this scenario.

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
