Question

Suppose a random variable x

is best described by a uniform probability distribution with range 2to 6 Find the value of a
that makes the following probability statements true.
P(x>a)=0.63

a=?

Answer 1

3.48

Explanation:

For a uniform distribution between 2 and 6:

P(x>a) = (6 − a) / (6 − 2)

P(x>a) = (6 − a) / 4

Given P(x>a) = 0.63:

0.63 = (6 − a) / 4

6 − a = 2.52

a = 3.48
