Exercise A: A hog raiser in a certain province uses two methods of pig-farming: intensive pig farming, where pigs are housed indoors in group-housing or straw-lines sheds; and extensive pig farming, where pigs are allowed to wander around the farm or fence. Test the hypothesis whether or not the mean weight of pigs in intensive farming is better than the extensive farming based from the mean weight of the pigs in the sample with data shown below. Use a one-tailed test at a = 1%. Intensive farming: X, = 85 kg, sỉ = 10 kg, and n, 55 Extensive farming: X, = 79 kg, s = 6 kg, and n, = 45 %3D

Question
Exercise A: A hog raiser in a certain province uses two methods of pig-farming: intensive pig farming,
where pigs are housed indoors in group-housing or straw-lines sheds; and extensive pig farming, where
pigs are allowed to wander around the farm or fence. Test the hypothesis whether or not the mean
weight of pigs in intensive farming is better than the extensive farming based from the mean weight of
the pigs in the sample with data shown below. Use a one-tailed test at a = 1%.
Intensive farming: X, 85 kg, sỉ = 10 kg, and n,
55
Extensive farming: X, = 79 kg, s = 6 kg, and n, =
45
