Problem 1 One of the advantages that concrete structures have over steel structures is fire resistance (which is to say, steel becomes weak when heated). The time, T, that it takes a steel girder to reach certain temperature (where its strength becomes too low to support its load) in a fire is, however, random. Suppose that for design code development, the following data have been gathered on the time T in hours: 0.736, 0.863, 0.865, 0.913, 0.915, 0.937, 0.983, 1.007, 1.011, 1.064, 1.109, 1.132, 1.140, 1.153, 1.253, 1.394 (a) Compute the values of the sample mean and the sample median by hand. (b) By how much could the smallest sample observation be increased without affecting the value of the sample median? (c) By how much could the smallest sample observation be increased without affecting the value of the sample mean? (d) Compute the values of the first quartile, third quartile, interquartile range, lower fence

Problem 2. Last year, in a sample of 1200 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product A, there are 300 of these people said they never did. This year, if a consumer sends in a rebate claim form, he will get 5 reward points. Observe 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product A this year, 200 of these people said they never did. a/ Does this data strongly suggest that the true proportion of such consumers who never apply for a rebate claim after purchasing the product A last year is greater than this year? Test the hypotheses at significance level 0.05 b/ Calculate an lower confidence bound at the 97% confidence level for the true proportion of such consumers who never apply for a rebate claim after purchasing the product A this year
Problem 4: Continuing with problem 3, a firm open to conduct a market research involving the proposed venture and using analytical tools can give an accurate information, thus gave the following info: Probability of a favorable market given a favorable study is 0.82 Probability of an unfavorable market given a favorable study is 0.18 Probability of a favorable market given an unfavorable study is 0.11 Probability of an unfavorable market given an unfavorable study is 0.89 Probability of a favorable research study is 0.55 Probability of an unfavorable research study is 0.45 Required: Develop a new decision tree for the doctors to reflect the options now open with the market study. Use the EMV approach to recommend a strategy. What is the expected value of information?
