There is a rough neighborhood with n 2 residents. each resident has to decide whether to engage in the crime of theft. if an individual chooses to be a thief and is not caught by the police, he receives a pay- off of w. if he is caught by the police, his payoff is z. if he chooses not to commit theft, he receives a zero payoff. assume that w> 0> z. all n residents simultaneously decide whether or not to commit theft. the probability of a thief being caught equals m, where m is the number of residents who choose to engage in theft. thus, the probability of being more crimes to investigate. the payoff from being a thief, given that m 1 other people have also chosen to be thieves, is then х. find all nash equilibria

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.

You want to have $80,000 in your savings account 11 years from now, and you’re prepared to make equal annual deposits into the account at the end of each year. if the account pays 6.30 percent interest, what amount must you deposit each year? (do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
