A process that manufactures steel bolts is supposed to be calibrated to produce bolts with a mean length of 5 cm. A sample of 100 bolts has a mean length of 5.02 cm with a standard deviation of 0.06 cm. Let μ be the mean length of bolts manufactured by this process. a) Find the P-value for testing H₀: μ = 5 versus H₁: μ ≠ 5. b) Do you believe it is plausible that the process is properly calibrated, or are you convinced that it is out of calibration? Explain.
