An average of 12 ounces of beer is used to fill each bottle in a local brewery as recorded. The manager now believes that, in general, beer bottles are overfilled. He takes a random sample of 30 bottles to test. The sample mean weight of the bottles is 12.8 ounces with a standard deviation of 1.5 ounces. Conduct a one-sample t-test to test whether the beer bottles are overfilled. Use 5% level of significance. (Round your steps to 4 decimal places, round the t test statistic to 3 decimal places)

1) A machine used to fill beverage cans is supposed to put exactly 12 ounces of beverage in each can, but the actual amount varies randomly from can to can. The population standard deviation is σ = 0.05 ounce. A simple random sample of filled cans will have their volumes measured, and a 99% confidence interval for the mean fill volume will be constructed. How many cans must be sampled for the margin of error to be equal to 0.01...

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...

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. Use this information and Excel functions to answer the following questions, and round your answers to four decimal places. a. What is the probability that the average fill of a...

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). H0: ...

If you have 4-liter bottle beer A, and 6 another liter of bottle beer B, and you need to measure exactly 2 liters of beer. The only actions you can do is to empty the bottle on the floor and to empty one bottle into the other. What are the initial state, state space, actions, goal test, path cost and the transition model (not to draw!!!)? The answer should be explained as a text only, without any drawing.

Sudz Beer buys the necessary ingredients to brew and bottle one batch of beer for a total of $24,300. Each batch yields 75,960 bottles of beer. The cost per bottle is $0.32. They sell their beer to a distributor with a 35% markup, and then the distributor sells it to the retailer for a 41% markup. Because the retailer has a virtual monopoly on consumer sales, they get away with selling the beer at a 62% margin. What is the...
