5. Suppose that Joe is a grocery store clerk. The time X (in minutes) that Joe spends checking out a randomly selected customer has probability density function (pdf) 5x4 ·e-(x/3)5 243 5x1 f (x) 0

Suppose you have the probability density function if 3 < x < 9 f(x) otherwise Find the cumulative distribution function of X. Select an answer ♥ F(x) if Select an answer if Select an answer Note: When writing your piecewise function, start with the left-most interval.

Data are distributed according to a probability density function f(x) = x. What is the probability density with random variable value x₁ = 1.3147? What is the probability density with given random variable value? f(x₁) = | 1 Do not leave any fields blank. If you don't know the answer, insert 1 for example. Insert only 3 most significant digits of your answer without rounding.
