the problem The weights of certain machine components are normally distributed with a mean of 8 81 g and a standard deviation of 0 06 g Find the two weights that separate the top 3 and the bottom 3 These weights could serve as limits used to identify which components should be rejected O 8 70 g and 8 92 g O 8 68 g and 8 97 g O 8 78 g and 8 84 g 8 80 g and 8 82 g
