- How common are financial cost or contractual constraints associated with smartphone ownership? A survey of smartphone users found that 48% of the 18- to 29-year-olds, 39% of the 30- to 49-year-olds, 24% 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 300 smartphone owners in each of the four age groups: 18 to 29, 30 to 49, 50 to 64, and 65 and older. Complete parts (a) through (c). a. At the 0.05 level of significance, is there evidence of a difference 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?

Too much staff and money is wasted, if there is not enough staff, and there are shortages and people must be diverted to another hospital at a loss of earnings to the hospital. The needs can change by both season and the week of the month. Staffing has always been the same for each of the spring months. In an effort to determine if this is reasonable, the number of occupied beds for the first week of each of these months is being compared. Is there evidence that the number of occupied beds remains constant the first week of each of these months?

The projects fall into two categories: shopping centers, and medical complexes. The typical work involved in each transaction is quite predictable and repetitive. The time requirements (unit loads) for preparing a standard contract of each type are given in the following table. Also listed are the number of professionals of each type and the number of available hours per professional per day (the rest of time is taken by other office activities): Unit load Shopping (hour/contract) Unit load Medical (hour/contract) No. of professionals Hours available (hours/professional /day) Paralegal 4 6 4 6 Tax lawyer 1 3 3 8 Senior partner 1 1 2 4 For the month of Feb 2023, the firm has generated the 150 orders, 75 of each type.

- 1. A microwave oven company has two factories in the east coast and the midwest. It takes 25 hours (including packaging, shipping, etc.) to transport the microwave ovens of each order from the factory on the east coast to the central warehouse, while it takes 20 hours from the factory in the Midwest to the central warehouse. Shipping from the East Coast factory to the central warehouse costs $80 per order, while shipping from the Midwest factory to the central warehouse costs $40. Now there are 1,000 hours available for packaging, shipping, etc., and $3,000 can be used as transportation costs. (a) Try to write a linear inequality system describing this transportation system. (b) Try to draw a graph of the linear inequality system and list the corner points.arrow_forwardHow common are financial cost or contractual constraints associated with smartphone ownership?
