6 ut of Allied Laboratories is combing some of its most common tests into one-price packages. One such package will contain three tests that have the following variable costs: Test A Test B Test C Disposable Syringe $4.00 $4.00 $4.00 Blood Vial $0.50 $0.50 $0.50 Forms $0.15 $0.15 $0.15 Reagents $0.80 $0.60 $1.20 Sterile Bandages $0.20 $0.20 $0.20 Breakage/losses $0.05 $0.05 $0.05 When the tests are combined, only one syringe, form, and sterile bandage will be used. Furthermore, only one charge for breakage/losses will apply. However, you will need three blood vials and three individual reagents (pay attention to the price of the regents). Assuming marginal cost pricing, what is the cost of the combined test? Select one or more: a. $8.50 O b. $8.00 O c. $6.90 O d. $4.50

Because of the severity of the storm and the type of residential construction used in this semitropical area, there was some concern that the average claim size would be greater than the historical average hurricane claim of $25,500. Several insurance companies collaborated in a data gathering experiment. They randomly selected 26 homes and sent adjusters to settle the claims. In the sample of 26 homes, the average claim was $28,000 with a population standard deviation of $6300. Is there sufficient evidence at a 0.01 significance level to support the claim that the home damage is greater than the historical average? Assume the population of insurance claims is approximately normally distributed. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho 25,500 Ha H. 25,500
