A company claims that the mean volume of the soda in its cans is 12.0 ounces. In a random sample of 8 of its cans, the mean is found to be 12.1 ounces. Based on past research, the population standard deviation is assumed to be 0.1 ounces. Test the claim that the mean is 12.0 ounces. Use a 0.01 level of significance. a) State the null and alternative hypotheses. b) Find the value of the test statistic. Use the appropriate...

Researchers studied the compression strength in lbs of 12-oz aluminum cans. A simple random sample of 35 aluminum cans filled with cola (which has more carbonation) had a sample mean compression strength of 554 lbs and a sample standard deviation of 15 lbs. A simple random sample of 30 aluminum cans filled with strawberry soda had a sample mean compression strength of 540 lbs and a sample standard deviation of 21 lbs. At the 0.05 significance level, perform a hypothesis...

(1 point) Cans of regular Coke are labeled as containing 12 oz. Statistics students weighed the contents of 9 randomly chosen cans, and found the mean weight to be 12.11 ounces. Assume that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 12.00 oz and a standard deviation of 0.1 oz. Find the probability that a sample of 9 cans will have a mean amount of at least 12.11 oz. u

A Coca-Cola bottling plant's product line includes 12-ounce cans of Coke products. The cans are filled by an automated filling process that can be adjusted to any mean filll volume and that will ll cans according to a normal distribution. However, not all cans will contain the same volume due to variation in the filling process. Historical records show that regardless of what the mean is set at, the standard deviation in ll will be 0.035 ounce. Operations managers at...
