Question

A company sells juice in one-quart bottles. In a quality control test, the company found the mean volume of juice in a random sample of bottles was x¯=31 ounces, with a margin of error of 3 ounces. Construct a confidence interval for the mean number of ounces of juice bottled by this company.

Answer 1

To construct a confidence interval for the mean number of ounces of juice bottled by the company, use the formula CI = X' ± Margin of Error.

Step-by-step explanation:

To construct a confidence interval for the mean number of ounces of juice bottled by the company, we can use the formula:

CI = X' ± Margin of Error

Given that the sample mean (X') is 31 ounces and the margin of error is 3 ounces, substituting these values into the formula gives:

CI = 31 ± 3

Therefore, the confidence interval for the mean number of ounces of juice is 28-34 ounces.
