Determining the Probability
Hi,
I have the following question and do not know where to look for an answer: Historical data indicates that the diameter of a ball bearing is normally distributed with a mean of 0.525 cm and a standard deviation of 0.008 cm. Suppose that a sample of 16 ball bearings are randomly selected from a very large lot. Determine the probability that the average diameter of a ball bearing is greater than 0.530 cm. Any help is appreciated. Thanks! :) |

Use the formula
Remember, you want greater than, so subtract from 1. |
