Unformatted text preview: Ho: P(heads) = 0.5 and HA : P(heads) not equal to 0.5. This gives E (heads) = E (Tails) = 17950/2 = 8975 under Ho. We will use alpha = 0.05. Using the formula presented above, X^2 heads = (O-E)^2/E 6 X^2 tails = (O-E)^2/E 6 so X^2 = 5.997103 + 5.997103 11.99 the critical value for X^2 df = 1, alpha = .05 = 3.84146 since X^2 > X^2df=1, alpha -= .05, we reject Ho. The p-value for this problem = .00053366 *...
