Consider the following data Enter the expected value EX Roun

Consider the following data: Enter the expected value E(X). Round your answer to one decimal place. Enter the value of P(X 3). Round your answer to one decimal place. Enter the value of P(X 6). Round your answer to one decimal place.

Solution

Question 6.7

E(X) = sum of xp(x) = 5.2

----------------------------------------------------

Part D

P(X>=3) = P(x=3 or 4 or 5 or 6 or 7) = 1

---------------------------------------------------

Part E

P(X<=6) = 1-P(X=7) = 0.7

--------------------------------------------

x p(x) xp(x) 3 0.2 0.6 4 0.2 0.8 5 0.1 0.5 6 0.2 1.2 7 0.3 2.1 1 5.2
