X-treme vitamin company is considering two investments, both of which cost $32,000. the cash flows are as follows: year project a project b 1 $ 34,000 $ 32,000 2 10,000 9,000 3 12,000 16,000 use appendix b for an approximate answer but calculate your final answer using the formula and financial calculator methods. a-1. calculate the payback period for project a and project b. (round your answers to 2 decimal places.) a-2. which of the two projects should be chosen based on the payback method? project a project b b-1. calculate the net present value for project a and project b. assume a cost of capital of 8 percent. (do not round intermediate calculations and round your final answers to 2 decimal places.) b-2. which of the two projects should be chosen based on the net present value method? project b project a c. should a firm normally have more confidence in the payback method or the net present value method? net present value method payback method

What is the difference between a public and a private corporation?

Annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). however, an exception occurs when the annuity payments come at the beginning of each period (termed an annuity due). what is the future value of a 13-year annuity of $2,800 per period where payments come at the beginning of each period? the interest rate is 9 percent. use appendix c for an approximate answer, but calculate your final answer using the formula and financial calculator methods. to find the future value of an annuity due when using the appendix tables, add 1 to n and subtract 1 from the tabular value. for example, to find the future value of a $100 payment at the beginning of each period for five periods at 10 percent, go to appendix c for n = 6 and i = 10 percent. look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 × 6.716)

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.
