Problem #3: Suppose we have two random variables: X~ N(4₁, of) and Y~ N(₂, 2). We collect a sample of size m = 12 X values and a sample of size n = 4 Y values, giving x = 3.7, sf = 1.8 and y = 4.4 and s2 = 2.8. Find a 90% confidence interval for of /a. The confidence interval is of the form (a, b). Enter the values of a and b (in that order) into the answer box below, separated with a comma.
