The average production cost for major movies is 67 million dollars and the standard deviation is 21 million dollars. Assume the production cost distribution is normal. Suppose that 9 randomly selected major movies are researched. Answer the following questions. Give your answers in millions of dollars, not dollars. Round all answers to 4 decimal places where possible. What is the distribution of X? X ~ N(,) What is the distribution of x¯? x¯ ~ N(,) For a single randomly selected movie, find the probability that this movie's production cost is between 64 and 67 million dollars. For the group of 9 movies, find the probability that the average production cost is between 64 and 67 million dollars. For part d), is the assumption of normal necessary? YesNo

EXERCISE 1.4 We have discussed the question of stability with respect to perturbations in the initial conditions. A model which is expressed as a differential equation may also involve coefficients based on measurements. Hence, it is also relevant to ask whether a solution is stable with respect to changes in coefficients. One example can be based on the problem of Exercise 1.2, $u'(t) = -\alpha u(t)$, $u(0) = u_0$. (1.57) 22 1. Setting the Scene We assume that $\alpha > 0$ is a measured number, and we consider a slightly perturbed problem $v'(t) = -(\alpha + \epsilon)v(t)$, $v(0) = u_0$. (a) We are interested in the solution at $t = 1$. Do small changes in $\alpha$ imply small changes in the solution? (b) Next we assume that both $u_0$ and $\alpha$ are measured. Discuss the stability of the problem (1.57) in this context.

Which of the following are TRUE statements? Select one or more correct answers. • Strict liability includes palming off. • None of these statements is true. • Disparagement is a type of intentional tort. • Through vicarious liability, the employer is liable for torts committed by their employees. On this basis employees are not liable for torts committed in the performance of their jobs. • If a buyer is harmed by goods that do not perform as promised, the buyer can only recover damages from the seller only if there is an express warranty. • A tortfeasor is an individual who commits a wrongful act that injures another, and is the defendant in a tort liability action.

The bromide-catalyzed reaction Br? H? + HNO? + C?H?NH? ? C?H?N?? + 2H?O is believed to have the following mechanism: Step 1: H? + HNO? \stackrel{k?}{\underset{k??}{?}} H?NO?? Step 2: H?NO?? + Br? \stackrel{k?}{?} ONBr + H?O Step 3: ONBr + C?H?NH? \stackrel{k?}{?} C?H?N?? + H?O + Br? Use the rate limiting step approximation to determine the form of the rate law. You may assume the first step rapidly equilibrates, the second step is slow, and the third step is fast. rate = Now use the steady-state approximation to determine the form of the rate law. Ignore the assumptions about the relative speed of the steps used in the previous question. rate =
