We will show in the next chapter that if x1 and x2 are independent with xi ∼ n (µi, σ2 i ), then x1 + x2 ∼ n (µ1 + µ2, σ2 1 + σ 2 2). use this result to find p(x < y ) for x ∼ n (a, b), y ∼ n (c, d) with x and y independent. hint: write p(x < y ) = p(x − y < 0) and then standardize x − y . check that your answer makes sense in the special case where x and y are i. i.d.

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
