Question

Your company prepares and distributes frozen foods. The package claims a net weight of 24.5 ounces. A random sample of today’s production was weighted, and the results were summarized as follows: average=24.41 ounces; standard deviation=0.11 ounce. Sample size=5 packages. Find the 95% confidence interval for the mean weight you would have found had you weighed all packages produced today. Interpret your results.

Answer 1

95% confidence interval = 62.60<u< - 2.45

Explanation:

0.11 + 2.53(5/4.94) = 62.60

0.11 - 2.53(5/4.94) = -2.45
