Best ResponseYou've already chosen the best response.0The Graduate Record Examinations are widely used to help predict the performance of applicants to graduate schools. The range of possible scores on a GRE is 200 to 900. The psychology department at a university finds that the scores of its applicants on the quantitative GRE are approximately normal with mean = 544 and standard deviation = 103. Use your calculator or computer to find the relative frequency of applicants whose score X satisfies the following conditions: (As part of your answer, draw a standard normal curve and shade the area under the curve that represented the answer to the question; do this on scratch paper and provide a onesentence description for the assignment). X < 500

Best ResponseYou've already chosen the best response.0Okay. So how would I properly describe it though? @Michele_Laino

Best ResponseYou've already chosen the best response.1now we have to compute the subsequent quantity: \[\Large t = \frac{{544  500}}{{103}} = ...?\]

Best ResponseYou've already chosen the best response.1yes! I think that you have to describe the steps in order to get my drawing above

Best ResponseYou've already chosen the best response.0So the 1st step is to compute the subsequent quantity?

Best ResponseYou've already chosen the best response.1ok! we can round off that result to 0.43

Best ResponseYou've already chosen the best response.1now we have to use the table of the "erf" function, and we get that the relative frequency is: \[\Large r = 50  16.28 = ...\% \]

Best ResponseYou've already chosen the best response.1yes! the first step is to compute the distance 0f 500 from the mean 544 in units of the standard deviation and yes! that percentage is the requested relative frequency
