A biologist believes that even-aged and uneven-aged conifer stands provide unique brood habitat for turkeys, resulting in a different brood survival rates for the two types of stands. Use the following data to test her claim that survival rate is different for even-aged and uneven-aged stands. Use a 1% level of significance. Compute the test statistic. Even-aged stands Uneven-aged stands X1 = 129 X2 = 86 n1 = 251 12 = 183
