Question

Suppose that you have a random variable Y that has outcomes which could be any number between 0 and 6 and a probability function that is a straight line that passes through the origin. Compute the appropriate values and fill in the table below (rounded to at least 3 decimals, when needed): $E(Y)$ $V(Y)$ median of Y 23rd percentile of Y 9th decile of Y

Step 1

Given that the probability function is a straight line passing through the origin and $ Y $ ranges from 0 to 6, we can assume the pdf $ f(y) $ is linear. Since it passes through the origin, the pdf can be represented as $ f(y) = ky $ for some constant \( k Show more…
