(Reading the N-, x-, -, F-tables)

(a) Given that X~N(2, 9), find P(-2

(b) If X to, find x; and x2 such that 

Note that in the last case we have several sets of x and x2. Find three sets.

(c) If XX, find x and x; such that P(X x)=0.95. Find two values x and x2 such that P(x) x) 0.05 and P(X> x)=0.01. Can you find x if you are told that P(X> x1)=0.50?

P(X < x1) = 0.95 P(-xxx) = 0.90 P(xXx2)=0.90
