Cans of Coke: A simple random sample of 36 cans of regular Coke has a mean volume of 12.19 oz. and a standard deviation of .11 oz. At the 1% significance level do the data provide sufficient evidence to conclude that the mean weight of the cans of Coke exceed 12 oz, as stated on the label.
Homework Answers
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: μ = 12
Alternative Hypothesis, Ha: μ > 12
Rejection Region
This is right tailed test, for α = 0.01 and df = 35
Critical value of t is 2.438.
Hence reject H0 if t > 2.438
Test statistic,
t = (xbar - mu)/(s/sqrt(n))
t = (12.19 - 12)/(0.11/sqrt(36))
t = 10.364
P-value Approach
P-value = 0
As P-value < 0.01, reject the null 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

Is the mean weight of regular Coke less than the mean weight of regular Pepsi? To test this claim, independent sets of cans of each brand were selected for testing. The sample statistics are summarized in the table below. The distributions of weights of regular Coke and regular Pepsi are approximately normal, and population variances are not equal. At the 5% significance level, what is the appropriate conclusion? a) Reject the null hypothesis; reject the claim that the mean weight...

of 0.14 oz and they appear be from a normally distributed
population. If the workers Want the filling process to work so that
almost all cans have volume between 11.88 and 12.52, and the

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...
