Data on the weights (lb) of the contents of cans
of diet soda versus the contents of cans of the regular version of
the soda is summarized to the right. Assume that the two samples
are independent simple random samples selected from normally
distributed populations, and do not assume that the population
standard deviations are equal. Complete parts (a) and (b) below.
Use a 0.05
significance level for both parts.

You are going to the store to get 14 cans of soda. There are 5
varieties to choose from, and you are to bring back at least 1 of
each variety. How many different assortments can you choose to come
back with?

1. You want to compare the contents of the soda cans. A random sample of 80 CC brand cans was randomly selected obtaining an average content of 355.9 ml with a standard deviation of 3.7 ml. While a random sample of 70 cans marks PC, an average content of 354.5 was obtained with a standard deviation of 9.7 ml.
a) Obtain the 95% confidence interval for the average content difference in the cans of both refresh brands.
b) Determine if...

In a plant that fills 12 ounce cans of soda, the mean fill
amount with the current machinery is 12.2 ounces with a standard
deviation of 0.03 ounces. A new machine is said to be more
accurate, so the company tested this new machine on a run of 10
cans, and obtained the following fill amounts:
12.03 12.10 12.02 11.92 12.10 12.00 12.05 11.97 11.99 11.87
Test the claim that the standard deviation of the new machine is
lower than...

Use the weights of cans of generic soda as sample one, and use
the weights of cans of the diet version of that soda as sample two.
Assume that the two samples are independent simple random samples
selected from normally distributed populations. Do not assume that
the population standard deviations are equal. Construct a 99%
confidence interval estimate of the difference between the mean
weight of the cans of generic soda and the mean weight of cans of
the diet...

(1 point) A certain type of soda has 200 calories in a one liter
bottle, on average. A small simple random sample of such bottles
has the following calorie measurements: 202 \ \ 205 \ \ 201 \ \ 202
\ \ 198 Four out of five measurements are over 200. Test the null
hypothesis that the average is 200 calories (assuming measurements
are Normally distributed). (a) What is the t-statistic? (Round to
three decimal places.) (b) What is the...
