Consider the case of a continous variable of interest, call it X. Its density function is given by 1 8192 (x-50)2 f(x) = 1 e 128 2 π What is the proportion of the population with an X value smaller than the 27-th percentile or greater than the 70-th percentile of this distribution? (Hint: Don't be impressed by f(x) or think that you have to employ some fancy calculus technique to find the answer. The answer can be found quickly. Just take a moment and think carefully.) Note well: Do not enter the % sign below. Just enter a number as in the following example: if the answer is 62.395%, then enter 0.62395 Answer: Consider the case of a continous variable of interest, call it X.
