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 is , and the table value of F Refer to Table 4-3 for critical values of F. The two sets of measurements come from populations with the same standard deviations. The two sets of measurements come from populations with different population means. The two sets of measurements come from 3 populations with the same population mean and different population standard deviations. 2.

Question 7 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 is and the table value of F - Refer to Table 4-3 for critical values of F. The two sets of measurements come from populations with the same standard deviations. The two sets of measurements come from populations with different population means. The two sets of measurements come from 3 populations with the same population mean and different population standard deviations. The two sets of measurements come from populations with different standard deviations. The two sets of measurements come from populations with the same population mean.
