Question
In an experiment to determine whether there is a systematic difference between the weights obtained with two different mass balances, six specimens were weighed, in grams, on each balance. The following data were obtained:
Specimen | A | B |
1 | 13.76 | 13.74 |
2 | 12.48 | 12.45 |
3 | 10.09 | 10.08 |
4 | 8.91 | 8.98 |
5 | 13.57 | 13.54 |
6 | 12.70 | 12.75 |
Can you conclude that the mean weight differs between the two balances? Use the α = 0.05 level of significance.
