A lab technician is tested for her consistency by making mutiple measurements of the cholesterol level in one blood sample. The targhet precision is a standard deviation of 1.1 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 greatear than the target at a = 0.01?
possible answers:

a) yes, since the X² test value 54.669 is greater than the criticval value 32w.000.

b) no, since the X² test value 28.64 is less than the critivcal value 30.576

c) yes, since the X² test value 54.669 is greater than the critical value 30.578

d) no since the X² test value 28.64 is less than the critical value 32.0900
