# Question: Three assembly lines are used to produce a certain component

Three assembly lines are used to produce a certain component for an airliner. To examine the production rate, a random sample of six hourly periods is chosen for each assembly line and the number of components produced during these periods for each line is recorded. The output from a statistical software package is:

a. Use a .01 level of significance to test if there is a difference in the mean production of the three assembly lines.

b. Develop a 99% confidence interval for the difference in the means between Line B and LineC.
