Alarge box contains 10,000 ball bearings. a random sample of 120 is chosen. the sample mean diameter is 10 mm, and the standard deviation is 0.24 mm. true or false: a. a 95% confidence interval for the mean diameter of the 120 bearings in the sample is 10 ± (1.96)(0.24)/√ 120. b. a 95% confidence interval for the mean diameter of the 10,000 bearings in the box is 10 ± (1.96)(0.24)/√120. c. a 95% confidence interval for the mean diameter of the 10,000 bearings in the box is 10 ± (1.96)(0.24)/√10,000.
