An experiment was conducted to compare the alcohol content of soy sauce on two different production lines. Production was monitored eight times a day. The data are shown below. Assume both populations are normal. It is suspected that production line 1 is not producing as consistently as production line 2 in terms of alcohol content. Test the hypothesis that
1=2
against the alternative that
12.
Use a P-value.
Production line 1: | 0.48 | 0.41 | 0.41 | 0.51 | 0.41 | 0.49 | 0.51 | 0.51 | |
---|---|---|---|---|---|---|---|---|---|
Production line 2: | 0.38 | 0.38 | 0.38 | 0.41 | 0.37 | 0.39 | 0.41 | 0.39 |
(A) CALCULATE THE TEST STATISTIC
(B) DETERMINE THE P - VALUE FOR THIS f- test.
