Question
Exercise 3.1 The orders from n = 100 customers for wooden panels of various thickness (X) are summarized as follows: Engr. A. CUH-ING Wooden Panel Thickness (X; inches) 1/8" 1/4" 3/8" No. of customer orders 20 70 10 Exercise 3.2 In Exercise 3.1, the following probabilities have been calculated: P(X=1/8) = 0.2, P(X=1/4) = 0.7, and P(X=3/8) = 0.1 Determine the cumulative distribution function of X and plot F(x). Exercise 3.3 Suppose that the probability density function of X is f (x) =. 0. 0<x<1 elsewhere Determine P(X < 1/3), P(1/3 <X<2/3), and P(X = 2/3). Engr. A. CUH-ING Exercise 3.4 In Exercise 3.3, the probability density function of X is f (x) = 3x2, I >x>0 elsewhere Determine the cumulative distribution function of X.
