The quality inspection team at a plant for medium size vehicles intends to compare the acceptable thickness of two types of brake pads. The expected thickness of the brake pads is 12 milli meters.

A sample size of 6 brake pads of each of the two types was randomly selected, and the results showing the thickness of the brake pads were sorted in ascending order, as shown in the table below:image text in transcribed

a. Calculate the mean, median, standard deviation and range for both types of brake pads.

b. Decide whether Type 1 or Type 2 brake pads meet the expectations set at 12 mm.

c. If the last value for the thickness for Type 2 brake pads is set at 24 mm, calculate the new values for parts (a) and (b) and explain the effect in the difference.
