A piston requires a valve diameter of 25mm

0.7mm in the specification document. The Tondex Fabricator Company has a process that produces pistons with mean valve diameters of 25mm and a standard deviation of 0.25mm, normally distributed. Currently Tondex maintains a quality control level that accepts middle 95% of the fabricated pistons over the normally distributed process parameter.

Find the proportion of the manufactured pistonsthat will pass specification requirements but not quality control.

Round off your answer to 2 decimal places. Put a zero '0' before the decimal point in your answer if needed.

The equivalent standard normal value at the lower specification limit is:

For the next 2 question enter your answer as "(valve diameter value) to (valve diameter value)". Example: 25.50 to 27.50.

The 1st range (lower range) of valve diameter values that represents passing specification requirement but not quality control is :

The 2nd range (higher range) of valve diameter values that represents passing specification requirement but not quality control is:

The proportion of the manufactured pistonsthat will pass specification requirements but not quality control :
