6 :)
no. of books: 1 2 3 4
combinations: 12, 13, 14, 23, 24, and 34
Get rid of all common factors.
36/4 = 9
x^9/x^7 = x^2
y^4/y^3 = y
Since 74% of the middle area is bounded, this means that
there is 13% on the left side, and another 13% on the right side.
P (left) = 0.13
P (right ) = 1 - 0.13 = 0.87
At this P values, the z scores are approximately:
z score (left) = -2.22
<span>z score (right) = 1.13</span>
