A biologist believes that even-aged conifer stands provide better brood habitat for turkeys, resulting in a higher survival rate compared to the brood habitat found in uneven-aged conifer stands. Use the following data to test her claim that survival rate is higher for even-aged stands. Use a 5% level of significance. Select the correct critical value. Even-aged stands Uneven-aged stands X1 = 131 X2 = 96 m1 = 251 n2 = 191
