    Standard Deviation

    I need help with this question below:

    A window frame maker test the first 1000 to see if the new latching system works correctly. Use the typical values for control limits.

    What % would be the expected outcome in a smaple mean that is within+ or - 3 standard deviation of the distribution mean?

    Thanks in advance,
