Suppose that a manufacturer needs to produce a custom aluminum housing for a special customer order. because it currently does not have the equipment necessary to make the housing, it would have to acquire machines and tooling at a fixed cost (net of salvage value after the project is completed) $250,000. the variable cost of production is estimated to be $5 per unit. the company can outsource the housing to a metal fabricator at a cost of $19 per unit. the customer order is for 7,000 units. what should it do?

The wall street journal reported that walmart stores inc. is planning to lay off 2,300 employees at its sam's club warehouse unit. approximately half of the layoffs will be hourly employees (the wall street journal, january 25-26, 2014). suppose the following data represent the percentage of hourly employees laid off for 15 sam's club stores. 55 56 44 43 44 56 60 62 57 45 36 38 50 69 65 (a) compute the mean and median percentage of hourly employees being laid off at these stores. (b) compute the first and third quartiles. (c) compute the range and interquartile range. (d) compute the variance and standard deviation. (e) do the data contain any outliers? (f) based on the sample data, does it appear that walmart is meeting its goal for reducing the number of hourly employees?
