An assembly process includes a torque wrench device that automatically tightens compressor housing bolts; the device has a known process standard deviation of ó = 3 lb-ft in the torque applied. A simple random sample of 35 nuts is selected, and the average torque to which they have been tightened is 150 lb-ft. What is the 95% confidence interval for the average torque being applied during the assembly process

  • statistics - ,

    .95 confidence interval for mean =

    Mean ± .196 Standard Error

    For calculation of SE, see previous post.

    I hope this helps. Thanks for asking.
