Osha uses a 5 dba exchange rate, meaning that the allowed exposure time is cut in half for every increase in exposure of 5 dba. acgih and niosh recommend a 3 dba exchange rate because noise energy exposure actually doubles every 3 dba. osha explains the use of the 5 dba exchange rate as a means to account for the time during a workday that the employee is not exposed to noise, like breaks. imagine you are a safety officer who has to choose which exchange rate is preferable to use at your organization. discuss in your journal entry whether the 5 dba or the 3 dba exchange rate should be used for controlling occupational noise exposure.

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
