A lab technician is tested for her consistency by making multiple measurements of the cholesterol level in one blood sample. The target precision is a standard deviation of 1.4 mg/dL or less. If 16 measurements are taken and the standard deviation is 2.1 mg/dL, is there enough evidence to support the claim that her standard deviation is greater than the target, at= .01?

Yes, since the ² test value 33.750 is greater than the critical value 32.000.

No since the X2 test value 22.50 is less than the critical value 30.578

No since the X2 test value 22.50 is less than the critical value of 32.000

Yes since the X2 test value 33.750 is greater than the critical value 30.578
