The last result in each set of data in Problem may be an outlier. Apply the Q test (95% confidence level) to determine whether or not there is a statistical basis to reject the result.
Problem
Consider the following sets of replicate measurements:
*A | B | *C | D | *E | F |
2.7 | 0.514 | 70.24 | 3.5 | 0.812 | 70.65 |
3.0 | 0.503 | 70.22 | 3.1 | 0.792 | 70.63 |
2.6 | 0.486 | 70.10 | 3.1 | 0.794 | 70.64 |
2.8 | 0.497 | 3.3 | 0.900 | 70.21 | |
3.2 | 0.472 | 2.5 |
Calculate the mean and the standard deviation for each of these six data sets. Calculate the 95% confidence interval for each set of data. What does this interval mean?
