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:	0.47	0.39	0.41	0.51	0.41	0.49	0.54	0.54
Production line 2:	0.39	0.37	0.39	0.41	0.38	0.38	0.41	0.39

(1 ) calculate the test statistic

(2) what is the p- value
