Document Summary

Economics 250 midterm test 1: answer guide: (a) y = 57 and h = 62. (b) first we need the deviations from the mean: y y. 198 y = 998/2 = 499 and sy = 22. 34; s2 h = 794/2 = 397 and sh = 19. 92; syh = 131. 5. 5. = 0. 295: (a) composing the 2x2 table of joint probabilities and adding up the entries gives 0. 05. The probability of 5 or more avoiding a recession is the probability of 5 or less having a recession. From table 3 that is 0. 834 or 83. 4%. (note: some readers interpreted at least half" to mean 6 or more; there the answer would be 0. 633, with a deduction. )
