A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. You collect the force data for 30 insulators selected for the experiment and find out that the mean force is 1670. The population mean force that you try to estimate is_______.
a. a confidence interval.
b. a statistic.
c. a point estimate.
d. a parameter.
e. an interval estimate.

An electronics company has a contract to deliver 21,475 radios within the next four weeks. The clientis willing to pay $20 for each radio delivered by the end of the first week, $18 for those delivered by theend of the second week, $16 by the end of the third week, and $14 by the end of the fourth week. Sinceeach worker can assemble only 50 radios per week, the company cannot meet the order with its presentlabor force of 40; hence it must hire and train temporary help. Any of the experienced workers can betaken off the assembly line to instruct a class of three trainees; after one week of instruction, each of the trainees can either proceed to the assembly line or instruct additional new classes.

At present, the company has no other contracts; hence some workers may become idle once the delivery is completed. All of them, whether permanent or temporary, must be kept on the payroll 'til the end of the fourth week. The weekly wages of a worker, whether assembling, instructing, or being idle, are $200; the weekly wages of a trainee are $100. The production costs, excluding the worker's wages, are $5 per radio. The company's aim is to maximize the total net profit.
