Juanita is pretty good with a post auger; she can dig the holes in 30 minutes. Gilberto is somewhat slow; it takes him 3 hours to dig the holes. Juanita earns $120 per hour as a psychiatrist, while Gilberto earns $25 per hour as a cobbler. Keeping in mind that either Juanita or Gilberto must take time off from work to dig the holes, who has the lower opportunity cost of completing the task?

At cooly cola, we are testing the appeal of our new diet one cola. in a taste test of 250 randomly chosen cola drinkers, 200 consumers preferred diet one cola to the leading brand. assuming that the sample were large enough, the large-sample 95% confidence interval for the population proportion of cola drinkers that prefer diet one cola would be:

Lambert manufacturing has $100,000 to invest in either project a or project b. the following data are available on these projects (ignore income taxes.): project a project b cost of equipment needed now $100,000 $60,000 working capital investment needed now - $40,000 annual cash operating inflows $40,000 $35,000 salvage value of equipment in 6 years $10,000 - both projects will have a useful life of 6 years and the total cost approach to net present value analysis. at the end of 6 years, the working capital investment will be released for use elsewhere. lambert's required rate of return is 14%. the net present value of project b is:
