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 mg/dL or less. If 18 measurements are taken and the standard deviation is 2 mg/dL, is there enough evidence to support the claim that her standard deviation is greater than the target, at α= .01? Group of answer choices No, since the χ2 test value 34.00 is less than the critical value 34.805. Yes, since the χ2 test value 68.000 is greater than the critical value 34.805. No, since the χ2 test value 34.00 is greater than the critical value 33.409. Yes, since the χ2 test value 68.000 is greater than the critical value 33.409.
