A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard devia
tion of 50. if 40 different applicants are randomly selected, find the probability that their mean is above 215. round your answer to four decimal places.
<span>Given data shows that mean of 200 and a standard deviation of 50. The probability that their mean is above 215 is calcualted by :
(215-200)/[50/sqrt(40)] = 1.8974
P(x-bar > 215) = P(z > 1.8974) = normalcdf(1.8974,100) = 0.0289.
if 40 different applicants are randomly​ selected, the probability that their mean is above 215 will be 0.0289.</span>

A mental set generally refers to the brain's tendency to stick with the most familiar solution to a problem and stubbornly ignore alternatives. This tendency is likely driven by previous knowledge (the long-term mental set) or is a temporary by-product of procedural learning (the short-term mental set).
