If the demand for a new product is estimated to be normally distributed with a mean of 200 and a standard deviation of 40, what is the probability that the demand will be less than 100 units? 0.1056 0.1113 0.1677 0.3830 None of the above is close Solution Z score = 100 - 200 /40 = -100/40 = -2.5 P(x<-2.5) = .0062 using z table at http://lilt.ilstu.edu/dasacke/eco148/ZTable.htm.
