Suppose the number of parking spots at urban grocery stores is uniformly distributed over the interval 90 to 140, inclusively (90 $\le$ x $\le$140), then the height of this distribution, f(x), is __________________.
A)1/90
B)1/50
C)1/140
D)1/200
E)1/500

Question

Quizplus · Accepted Answer

The height of a uniform distribution is calculated as 1/(b-a), where [a, b] is the interval over which the variable is uniformly distributed. Here, a = 90 and b = 140, so the height is 1/(140-90) = 1/50.
