Philip Carey Co. owned a tract of land in Plymouth Township, Pennsylvania, on which it deposited a large pile of manufacturing waste containing asbestos. Carey sold the land to Celotex, and Celotex sold the land to Smith Land & Improvement Corp.. The EPS notified Smith that unless it took steps to eliminate the asbestos hazard, the EPA would do the work and pursue reimbursement. Smith cleaned up the land to the EPA’s satisfaction at a cost of $218,945,44. Smith asked Celotex and Carey for reimbursement. Which firms have liability for the cleanup costs? PROVIDE A brief restatement of the legal question posed

15.24 A field experiment was conducted to assess the effect of two methods for reducing car speed on a particular section of road. Method 1 involved using parked police cars (with no actual police officer in the car) and Method 2 involved active patrolling by a police car. For each method, the speeds of eight randomly selected cars driving through the section were recorded and are given here: Method 1 69 73 80 71 82 79 74 78 Method 2 72 68 74 70 76 71 67 75 Assume that the speeds of cars under each method are values of a random sample that can be modeled with a density, but the assumption of normality is not appropriate. (a) State the appropriate hypotheses for a test aimed at determining whether the distribu- tion of speeds under Method 1 are significantly higher than the speeds under Method 2. (b) What is the expected value of the test statistic when the null hypothesis is true? (c) Calculate the observed test statistic, give the $p$-value for your test in (a) and state your decision, using a 10% significance level. Show all details clearly. (d) Suppose that you could assume the two independent random samples each come from a normal population with common population standard deviation. What test statistic would you use to assess whether the speeds under Method 1 are significantly higher than the speeds under Method 2? (Just give the formula for the test statistic; do not compute the test-statistic value.)
