Agricultural scientists are testing a new pig feed to determine whetherit increases the pigs' weights. The scientists divided a herd of20
pigs into two random groups, where10
of the pigs are fed withthe new feed, while the other10
pigs were fed with their regularfeed. The following table shows the weight gain after 6months for both groups of pigs. Assume that the population standard deviation of weight gained is10
pounds for both groups, and assume that the weight gains arenormally distributed. Let the weight gained by thepigs fed with the news feed be the first sample, and let the weight gained by thepigs fed withthe regular feed be the second sample. At the0.01
level of significance, is there evidence that the new feed increases the amount of weight gained? Perform the test using a TI-83, TI-83 Plus, or TI-84 calculator. Find the test statistic, rounded to two decimal places, and the p-value, rounded to three decimal places.
