a)
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: μ = 12
Alternative Hypothesis, Ha: μ ≠ 12
b)
Test statistic,
t = (xbar - mu)/(s/sqrt(n))
t = (12.025 - 12)/(0.0727/sqrt(8))
t = 0.973
c)
P-value Approach
P-value = 0.3630
d)
As P-value >= 0.05, fail to reject null hypothesis.
e)
There is not sufficient evidence to conclude that the mean
differs from 12 ounces

The production manager at Sunny Soda, Inc. is interested in tracking the quality of the company’s 12-ounce bottle filling line. The bottles must be filled within the tolerances set for this product because the dietary information on the label shows 12 ounces as the serving size. The design standard for the product calls for a fill level of 12.00 ± 0.10 ounces (11.90 to 12.10 ounces). The manager collected the following sample data (in fluid ounces per bottle) on the...

8. From a population of cans of coffee marked "12 ounces," a sample of 125 cans is selected and the contents of each can are weighed. The sample revealed a mean of 11.8 ounces and a standard deviation of 2.0 ounces. Test to see if the mean of the population is at least 12 ounces. Use .05 level of significance. deviation of 2.0 un an are weighed. The sample essa sample of 125 cans is selected and Ho: u 2...
A machine is used to fill 12 oz. cans. A can is selected every two minutes and the weight of the can is obtained. It is known that the process standard deviation is 0.1 oz. The observations are shown in the accompanying table.

Quality Associates, Inc., a consulting firm, advises its clients about sampling and statistical procedures that can be used to control their manufacturing processes. In one particular application, a client gave Quality Associates a sample of 800 observations taken during a time in which that client’s process was operating satisfactorily. The sample standard deviation for these data was .21; hence, with so much data, the population standard deviation was assumed to be .21. Quality Associates then suggested that random samples of...
