5. Here are measurements (in millimeters) of a critical dimension for 16 auto engine crankshafts.

224.12, 224.001, 224.017, 223.982, 223.989, 223.961, 223.96, 224.089, 223.987, 223.976, 223.902, 223.98, 224.098, 224.057, 223.913, 223.999

The dimension is supposed to be 224 mm and the variability of the manufacturing process is unknown. Is there evidence that the dimension is not 224 mm? State H0 and Ha and carry out a t test. You must include SPSS output in your response. What do you conclude (which hypothesis do you support)?
