Alab technician is tested for her consistency by making multiple measurements of the cholesterol level in one blood sample. the larger precision is a standard deviation of 1.35 mg/dl or less. if 14 measurements are taken and the standard deviation is 1.5 ml/dl, is there enough evidence to support the claim that her standard deviation is greater than the target at a=0.01?
