- Problem 3 Eight Measurements Were Made On The Inside Diameter Of Forged Piston Rings Used In An Automobile Engine The 1 (32.79 KiB) Viewed 150 times
Problem 3. Eight measurements were made on the inside diameter of forged piston rings used in an automobile engine. The data (in millimeters) are 74.001, 74.003, 74.015, 74.000, 74.005, 74.002, 74.005, and 74.004. a. Calculate the sample mean and sample standard deviation. b. Construct a dot diagram of the data and comment on the data. c. Construct a normal probability plot of the piston ring diameter data given. Does it seem reasonable to assume that piston ring diameter is normally distributed? (You may use excel for your computations. Copy paste your excel document.)
