Question

For the given question solve the following:

(a) Construct the cumulative distribution function.
(b) What is the expected value, variance, and standard deviation of this random variable?

A random variable $ X $ takes values between 4 and 6 with a probability density function $ f(x) = \frac{1}{x \ln(1.5)} $ for $ 4 \leq x \leq 6 $ and $ f(x) = 0 $ elsewhere.

Expression, rule, or law that gives the relationship between an independent variable and dependent variable. Some important types of functions are injective function, surjective function, polynomial function, and inverse function.
