How common are financial cost or contractual constraints associated with smartphone ownership? A survey of smartphone owners found that 48% of the 18- to 29-year-olds, 38% of the 30- to 49-year-olds, 25% of the 50- to 64-year-olds, and 19% of those age 65 or older have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion. Suppose the survey was based on 200 smartphone owners in each of the four age groups: 18 to 29, 30 to 49, 50 to 64, and 65+. a.  At the 0.05 level of significance, is there evidence of a differ-ence among the age groups in the proportion of smartphone owners who have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion? b. Determine the p-value in (a) and interpret its meaning. c.  If appropriate, use the Marascuilo procedure and a=0.05 to determine which age groups differ.

8) Send With Us is a company that ships large packages overnight to cities all over the country. Overnight delivery is guaranteed. They charge for delivery depending on the weight of the package according to the following price list: $30 per pound for packages weighing up to and including 10 pounds. $25 per pound for packages weighing more than 10 pounds and up to and including 20 pounds $20 per pound for packages weighing more than 20 pounds and up to and including 30 pounds. $15 per pound for packages weighing more than 30 pounds. a) Sketch a graph of the function that describes the cost of all possible shipping charges. b) If the package you want to ship weighs 15 pounds and there is an 8% tax on all shipping charges, what will be your total cost?

17. A manager of an inventory system believes that inventory models are important decision-making aids. The manager has experience with the EOQ policy, but has never considered a backorder model because of the assumption that backorders were "bad" and should be avoided. However, with upper management's continued pressure for cost reduction, you have been asked to analyze the economics of a backorder policy for some products that can possibly be backordered. For a specific product with D = 800 units per year, C. = $150, C₁ = $3, and C₁ = $20, what is the difference in total annual cost between the EOQ model and the planned shortage or backorder model? If the manager adds constraints that no more than 25% of the units can be backordered and that no customer will have to wait more than 15 days for an order, should the backorder inventory policy be adopted? Assume 250 working days per year.

An insurance company offers four different deductible levels-none,low, medium, and high-for its homeowner's policyholders and threedifferent levels-low, medium, and high-for its automobilepolicyholders. The accompanying table gives proportions for the variouscategories of policyholders who have both types of insurance. Forexample, the proportion of individuals with both low homeowner'sdeductible and low auto deductible is .06 (6% of all such individuals).   Homeowner's Auto N L M H LMH .04.07.02 .06.10.03 .05.20.15 .03.10.15 Suppose an individual having both types of policies is randomlyselected.a. What is the probability that the individual has a medium auto deductible and a high homeowner's deductible?b. What is the probability that the individual has a low autodeductible? A low homeowner's deductible?c. What is the probability that the individual is in the samecategory for both auto and homeowner's deductibles?d.
