A large box contains 10000 ball bearings. A random sample of 120 is chosen. The sample mean diameter is 10 mm and the standard deviation is 0.24 mm. Is the following statement true or false? A 95% confidence interval for the mean 0.24 diameter of the 120 bearings in the sample is 10 ± 1.96- V120 mm. True False
