In: Economics
Find a 90% confidence interval for the mean volume of the filled bottle contents.
SCENARIO 8-12
The Three Brothers Energy Drink Company bottles and distributes a
popular drink for athletes and exercise enthusiasts. Because of its
marketing successes the company has installed an additional filling
machine and the managers are eager to use it in daily operations.
The machine is set to fill bottles at 16 oz.
However, we know there is inherent machine variability and quality
control has determined through testing a mean of 16.2 oz. and a
standard deviation of 0.3 oz. using a 100 bottle sample.
Refer to Scenario 8-12.
Find a 90% confidence interval for the mean volume of the filled
bottle contents.
