A local brewery distributes beer in bottles labeled 24 ounces. A government agency thinks that the brewery is cheating its customers. The agency selects 40 of these bottles, measures their contents, and obtains a sample mean of 23.8 ounces with a standard deviation of 1.1 ounces. Use a 0.01 significance level (α = 0.01) to test the agency's claim that the brewery is cheatings its customers (that the average volume of their beers is less than 24 ounces).

A local brewery sells their beer in 330 ml bottles. On average the beer is filled with 328.1 ml with a standard deviation of 0.9 ml. Since it is possible to under-fill the bottle but impossible to fill the bottle with more than 330 ml, the distribution is skewed left.

A brewery produces cans of beer that are supposed to contain exactly 12 ounces. But owing to the inevitable variation in the filling equipment, the amount of beer in each can is actually a random variable with a normal distribution. It has a mean of 12 ounces and a standard deviation of .30 ounce. If you bought a six-pack of their beer what is the probability that you are going to actually get less than or equal to a total...
