1. The probabilities of three genotypes XX, XY and YY are theta^2, 2 theta(1 - theta) and (1 - theta)^2 for some theta. In a study of 3,000 individuals, the frequencies of the three genotypes are: The maximum likelihood estimate for theta is 0.7281 Which of the following is a 10% significance region for theta, based on the chi-squared statistic (i) [0.7137,0.7410] (ii) [0.7201,0.7322] (iii) [0.7201,0.7359] (iv) [0.7235,0.7322] (v) [0.7235,0.7410]

Solution

(III) is correct
