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-lined 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 𝛼 = 1%. Determine the Zcritical value of the problem above.
Write a program which consists of a single class called BuyStuff that asks the user for two amounts, adds them, calculates tax at 15%, shows the result to the user, and asks for money.
