Design specification for a soft drink filling machine is to fill bottles with 12 ounces of soft drink. A random sample of 49 bottles filled by this machine was sampled and the contents measured. If this sample had a mean measurement of 11.9 ounces with a standard deviation of 0.28 ounces, is the machine really under-filling bottles? Test at a 5% significance level.

    A soft drink vending machine, when in perfect adjustment, fills bottles with 12 ounces of soft drink. A random sample of 25 bottles is selected, and the contents are measured. The sample yielded a mean content of 11.88 ounces, with a sample standard deviation of 0.24 ounce. With a .05 level of significance, test to see if the machine is in perfect adjustment. Assume the distribution of the population is normal. Group of answer choices t = -2.5; therefore, reject...

    Soft drink cans are filled by an automated filling machine and the standard deviation is 0.5 fluid ounce. Assume that the fill volumes of the cans are independent, normal random variables. Round your answers to four decimal places (e.g. 98.7654). If the mean fill volume is 12.1 fluid ounces, what should the standard deviation of fill volume equal so that the probability that the average of 100 cans is less than 12 fluid ounces is 0.005?

    A local brewery distributes beer in bottles labeled 24 ounces. A government agency thinks that the brewery is cheating its customers. The agency selects 50 of these bottles, measures their contents, and obtains a sample mean of 23.6 ounces with a standard deviation of 0.8 ounces. Use a 0.01 significance level (α = 0.01) to test the agency's claim that the brewery is cheating its customers (that the average volume of their beers is less than 24 ounces). H0: Ha:...

    Suppose a brewery has a filling machine that fills 12-ounce bottles of beer. It is known that the amount of beer poured by this filling machine follows a normal distribution with a mean of 12 ounces and a standard deviation of 0.08 ounce. Use this information to answer the questions that follow. Imagine that all possible samples of size 25 are taken from the population of this brewery's 12- ounce bottles of beer. Describe the sampling distribution of 2. i....

    A soda bottling plant fills cans labeled to contain 12 ounces of soda. The filling machine varies and does not fill each can with exactly 12 ounces. To determine if the filling machine needs adjustment, each day the quality control manager measures the amount of soda per can for a random sample of 50 cans. Experience shows that its filling machines have a known population standard deviation of 0.35 ounces. In today's sample of 50 cans of soda, the sample...

    1. A cereal box filling machine is designed to release an amount of 12 ounces of cereal into each box, and the machine's manufacturer wants to know of any departure from this setting. The engineers at the factory randomly sample 100 boxes of cereal and find a sample mean of 12.25 ounces. If we know from previous research that the population is normally distributed with a standard deviation of 1.51 ounces, is there evidence that the mean amount of cereal...
