Document Summary
L (x) = xe x + e x = 0 = e x( x + 1) = 0 = = 1 x . If it is equally likely for any horse to win from any slot number, then out of 160 races we"d expect 20. = (11 20)2 horses to win from each slot, i. e. , ei = 20 for i = 1, 2, . 05,7 = 14. 067 we can reject the null hypothesis and claim there is su cient evidence that not all horses have an equally likely chance of winning from any slot number. Under the null hypothesis of the 400 maples we"d expect 40 to be birdseye, 80 to be amed and 280 to be straight grained. We compute the chi-square statistic 2 = p3. 05,2 = 5. 991 there is not enough evidence to reject the theoretical model. 5. 3333 + 5. 3333 + 1. 3333 + 12 = 24 2.
