I compared Coke and Pepsi cans. For Coke I have n= 36 sample mean = 12.19 oz. and s = .11. For the Pepsi cans I have n=36 sample mean = 12.29 oz. and s =.09. I wish to determine if the two brands provide the same volume per can.
1. Is it reasonable to pool the sample variances? Why or why not?

How many degrees of freedom for this problem

Compute s_pool

Compute the margin of error for the confidence interval

Test the claim that µ_coke = µ_pepsi for α = .05

A random sample of 36 cans of regular Coke had a sample mean of 12.19 oz with a standard deviation of 0.11 oz. A sample of 36 cans of regular Pepsi had a sample mean of 12.29 oz with a standard deviation of 0.09 oz. Find a 90% confidence interval for the difference in volume between cans of regular Coke and cans of regular Pepsi.

Cans of regular coke are labled to indicate they contain 12 oz. Lets say we have a sample n=36 with mean 12.19 oz. Assuming u=12oz and zigma=0.11oz, find the probablity that a sample of 36 cans will have a mean of 12.19 oz or greater. Do the results indicate an unusual event?

Suppose you randomly sample 64 cans and find the mean amount of Coke in this sample is 11.85 ounces and the standard deviation is 0.35 ounces. Construct a 95% confidence interval estimate for the mean amount of Coke in the all such cans.

Cans of regular Coke are labeled as containing 12 oz. Statistics students weighted the content of 8 randomly chosen cans, and found the mean weight to be 12.14. 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 0.09 oz. Find the probability that a sample of 8 cans will have a mean amount of at least 12.14 oz.

Cans of regular Coke are labeled as containing 12 oz. Statistics students weighed the contents of 7 randomly chosen cans, and found the mean weight to be 12.12 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 0.09 oz. Find the probability that a sample of 7 cans will have a mean amount of at least 12.12 oz.

Suppose you have a sample of 36 observations with the sample mean = 2 and the sample standard deviation = 7. Compute the t-statistic corresponding to these values for the null hypothesis that mean = 0. Test two-sided alternative hypothesis that mean 6= 0. Do you reject the null hypothesis at p = 0:05? At p = 0:01? If the sample size is reduced to 25, do you get the same conclusions?

(1.) A normal population has a mean of µ = 100. A sample of n = 36 is selected from the population, and a treatment is administered to the sample. After treatment, the sample mean is computed to be M = 106. Assuming that the population standard deviation is σ = 12, use the data to test whether or not the treatment has a significant effect. Use a one tailed test. Hypothesis: Zcrit= z test calculation: Conclusion: (2.) A mood questionnaire...
