Question
Doris and Sakar, the co-directors of manufacturing at a soft drink bottling factory, need to determine whether a new filling machine is injecting the appropriate amount of cola into 16-ounce bottles. They select a random sample of 35 bottles and calculate the mean amount of cola fill to be 15.9 ounces with a standard deviation of 0.40 ounces. Let mu = true average amount of cola fill.
QUESTION 3
Using the appropriate Minitab printout (attached to One-Sample Table below), what is the p-value?
0.070
0.074
0.139
0.148
None of the above.
QUESTION 4
Using the p-value approach, what is the appropriate rejection region?
Reject H0 if p-value > 2.262 or if p-value < - 2.262
Reject H0 if p-value > 1.96 or if p-value < - 1.96
Reject H0 if p-value < = 0.05
Reject H0 if p-value < = 0.025
None of the above.
1 points
QUESTION 5
What is the appropriate conclusion?
Reject H0 so one can conclude the true mean amount of cola fill is less than 16 ounces.
Do not reject H0 so one cannot conclude the true mean amount of cola fill is significantly different from 16 ounces.
Do not reject H0 so one can conclude the true mean amount of cola fill is significantly different from 16 ounces.
Reject H0 so one can conclude the true mean amount of cola fill is significantly different from 15.9 ounces.
None of the above.
QUESTION 6
Use the One-Sample Table below to find a 90% confidence interval for the true average amount of cola fill.
(15.7888, 16.0112)
(15.7675, 16.0325)
(15.7857, 16.0143)
(15.7626, 16.0374)
None of the above
QUESTION 7
Interpret the interval in Exercise 6.
One can be 90% confident that the true average amount of cola fill is between 15.7888 ounces and 16.0112 ounces.
One can be 90% confident that the true average amount of cola fill is between 15.7675 ounces and 16.0325 ounces.
One can be 90% confident that the true average amount of cola fill is between 15.7857 ounces and 16.0143 ounces.
One can be 90% confident that the true average amount of cola fill is between 15.7626 and 16.0374 ounces.
None of the above.
