A business is considering a cash outlay of $250,000 for the purchase of land, which it could lease for $36,000 per year. If alternative investments are available which yield an 18% return, the opportunity cost of the purchase of the land is:

Hours to produce one unit worker hours to produce yarn country a 8 hours country b 4 hours worker hours to produce fabric counrty a 12 hours country b 13 hours additional worker hours to produce fabric instead of yarn country a ? country b? which of the follow is true of the trade relationship between country a and country b? country a has an absolute advantage in producing yarn and fabric country b has an absolute advantage in producing yarn and fabric country b has a comparative advantage to country a in producing fabric country a has a comparative advantage to country b in producing fabric

Reliability and validity reliability and validity are two important considerations that must be made with any type of data collection. reliability refers to the ability to consistently produce a given result. in the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. to illustrate this concept, consider a kitchen scale that would be used to measure the weight of cereal that you eat in the morning. if the scale is not properly calibrated, it may consistently under- or overestimate the amount of cereal that’s being measured. while the scale is highly reliable in producing consistent results (e.g., the same amount of cereal poured onto the scale produces the same reading each time), those results are incorrect. this is where validity comes into play. validity refers to the extent to which a given instrument or tool accurately measures what it’s supposed to measure. while any valid measure is by necessity reliable, the reverse is not necessarily true. researchers strive to use instruments that are both highly reliable and valid.

Depasquale corporation is working on its direct labor budget for the next two months. each unit of output requires 0.61 direct labor-hours. the direct labor rate is $8.70 per direct labor-hour. the production budget calls for producing 6,700 units in may and 7,100 units in june. if the direct labor work force is fully adjusted to the total direct labor-hours needed each month, what would be the total combined direct labor cost for the two months?
