iew Let X be the same continuous random variable from before: f ( x ) = { 3 x 0 ≤ x ≤ 3 0 otherwise (d) Find the CDF of X. (e) Draw a labeled sketch of the CDF of X. (f) Use the CDF to compute P(X > 2). Poll Question 7.4 Percentiles DEFINITION: Let p be a number between 0 and 1. The 100th percentile of the distribution of a continuous random variable X, denoted by n(p), is defined by n(p) p = F(n(p)) = [ f(x)dx x- That is, n(p) is the number on the x-axis, such that the shaded area under f(x) to the left of n(p) has size p. DEFINITION: The 50th percentile is also called the MEDIAN. Example: (cont.) (g) Find the 75th percentile for the continuous random variable X above.
