Question

Problem 4. Say the distributions of $X_1$ and $X_2$ are $N(17.88, 15.6)$ and $N(14.35, 12.89)$, respectively. What is the probability that $2X_1$ exceeds $X_2$ by 20? That is, find $P(2X_1 > X_2 + 20)$, assuming independence of $X_1$ and $X_2$. (Note: 15.6 and 12.89 are variances).

Step 1

For 2X: Mean = 2 * 17.88 = 35.76 Variance = 2^2 * 15.6 = 62.4 For X: Mean = 14.35 Variance = 12.89 Show more…

Say the distributions of x_(1) and x_(2) are N(17.88,15.6) and N(14.35,12.89), respectively. What is the probability that 2x_(1) exceeds x_(2) by 20? That is, find P(2x_(1)>x_(2)+20),assuming independence of x_(1) and x_(2). (Note: 15.6 and 12.89 are variances). Problem 4. Say the distributions of X and X2 are N(17.88,15.6) and N(14.35, 12.89), respec- tively. What is the probability that 2X exceeds X by 20? That is, find P(2X > X + 20) assuming independence of X and X2.(Note:15.6 and 12.89 are variances)
