QUESTION 6 Suppose that you wanted to determine whether the returns of each firm were statistically different from zero. Order the steps of the hypothesis testing procedure: v Reject or fail to reject the null. Interpret the result. v State the null and alternative hypothesis. v Calculate the test statistic. v State the level of significance of the test. v Determine the critical values and/or p-values.

3)Suppose we are testing a null hypothesis against a two-sided alternative, then the alternative can be written as: A. E(Y) > μY,0 B. E(Y) = μY,0 C. ≠ μY,0 D. E(Y) ≠ μY,0
26. A mail order company has conducted a survey to assess whether at least 95% of their customers are satisfied with their most recent order. The results show that of the 280 customers asked, 270 said they were satisfied, with the final 10 saying they were dissatisfied. They have asked you to A conduct a hypothesis test at the 5% level to assess whether there is sufficent evidence to show that more than 95% of their customers are satisfied. What should your null and alternative hypotheses be? Ho:u = 0.95 H1:µ > 0.95 Ho:µ > 0.95 H:µ = 0.95 Ho:u 0.95 = 0.95 H: µ + 0.95 Ho:µ + 0.95 H:µ = 0.95

Parker Plaintiff is in a hurry and stops by a convenience store for a drink. The store is out of her favorite brand of soda, so Parker decides to go elsewhere. Before Parker can leave, she is stopped by a store employee that accuses her of shoplifting. The employee escorts Parker to a small room in the back of the store and tells Parker that if she attempts to leave the room, she will be arrested and sent to jail. Parker waits for over an hour before the manager tells her that she is free to go. What advice would you give Parker? Discuss the possible tort claim Parker might have against the store. Be sure to include the elements of the tort and relate those elements to the scenario. If Parker decides to pursue a claim against the store, should she consider a lawsuit, mediation, or arbitration? explain why your choice is the best option.
4. From experience it is known that a certain brand of tyre lasts, on average, 15,000 miles with standard deviation 1250. A new compound is tried and a sample of 120 tyres yields an average life of 15,150 miles, with the same standard deviation. Are the new tyres an improvement? Use the 5% significance level. Show hypothesis testing by step-by-step.
