Suppose a consumer group suspects that the proportion of households that have three or more cell phones is 0.71. A cell phone company has reason to believe that the proportion is not 0.71. Before they start a big advertising campaign, they conduct a hypothesis test. Their marketing people survey 107 households with the result that 83 of the households have three or more cell phones. What is the test statistics to test the Null hypothesis Ho: p = 0.71 against the alternative, Ha: p * 0.71?

Chic Department Store has a new promotional program that offers a free gift-wrapping service for its customers. Chic's customer-service department has practical capacity to wrap 7,500 gifts at a budgeted fixed cost of $6,750 each month. The budgeted variable cost to gift wrap an item is $0.30. During the most recent month, the department budgeted to wrap 6,750 gifts. Although the service is free to customers, a gift-wrapping service cost allocation is made to the department where the item was purchased. The customer-service department reported the following for the most recent month: (Click the icon to view the actual and budgeted units.) Read the requirements. Requirement 1.
