Edwards manufacturing company purchases two component parts from three different suppliers. the suppliers have limited capacity, and no one supplier can meet all the company’s needs. in addition, the suppliers charge different prices for the components. component price data (in price per unit) are as follows: supplier component 1 2 3 1 $10 $15 $14 2 $13 $12 $10 each supplier has a limited capacity in terms of the total number of components it can supply. however, as long as edwards provides sufficient advance orders, each supplier can devote its capacity to component 1, component 2, or any combination of the two components, if the total number of units ordered is within its capacity. supplier capacities are as follows. supplier 1 2 3 capacity 1500 2500 2000 if the edwards production plan for the next period includes 2,000 units of component 1 and 3,000 units of component 2, what purchases do you recommend

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.
