An ore sample was analyzed for its Fe content. Student A analyzed the sample a total of six times and her results had a standard deviation of 1.33. The same sample was analyzed five times by Student B and his results had a standard deviation of 3.42. To determine if their standard deviations are similar, they perform an F test. The calculated F value is , and the table value of Fis Refer to Table 4- 3 in your book for critical values of F. O 6.61; 7.39 ○ 6.61; 9.36 O 0.151; 9.36 O 2.57; 7.39 6.61; 6.98
