here are measurements

here are measurements of critical dimension for a random sample of 16 auto engine crankshafts: 224.120, 224.089, 223.913, 224.001, 223.987, 223.999, 224.017, 223.976, 223.982, 223.902, 223.989, 223.980, 223.961, 224.098, 223.960, 224.057 the data come from a production process that is known to have a standard deviation of sigma = 0.060 mm. the process mean is supposed to be mu=224 mm but can drift away from this target during production. is there sufficient evidence to conclude that the mean dimension is not 224 mm? give appropriate statistical evidence to support you conclusion.
