Question
The intelligence quotient (1.Q) of a large number of students is normally distributed with mean 100
and standard deviation 10.
Suppose that students having an 1.Q of 119.6 or higher are considered "gifted".
Let Y be the number of "gifted" students out of a random sample of 4 independent students, and F
be the percent of failing courses in a program, where:
F=1-y2
Compute the coefficient of variation of Y (in %)
Important: Use 8 or 9 decimals in all your intermediate computations.
(Enter your answer in % using two decimal places. For "540.72 %", you would write 540.72). Do not
round.
