What is Mean ?

Mean refers to the central tendency of a data set. It is calculated by taking average of the data.

It is given that

any bolts that are more than 2 standard deviations from the mean will be destroyed

Mean = 7 cm

Standard Deviation is = 0.10 cm

The length of the bolt which is not acceptable is = Mean + 2 Standard Deviation.

Length = 7 + 2 * 0.10

Length = 7.2 cm

Therefore if the bolt of length more than 7.2 cm will be destroyed.
