The produce section of a grocery store stocks 2-pound bag of carrots, and it occassionally likes to do a quality assurance check. Recently, 5 randomly selected bags of carrots were pulled from stock -- their weights are shown below:

1.93	2.18	2.2	2.24	1.9

Find a 99% confidence interval for the mean weight of bags of carrots sold by this store. Use interval notation, smaller number first, with each number rounded to two decimal places.

(, )

Based on this confidence interval, should the grocery store be satisfied with the "2-pound" labeling?

No. Since the entire confidence interval is entirely below 2.0, the store could be charging customers too much.
No, because the confidence interval includes 2.0.
No. Since the confidence interval is entirely above 2.0, the store could be losing money.
Yes. Since the confidence interval does not contain 2.0, it is plausible that the true average of all bags is 2 lbs.
Yes. Since the confidence interval contains 2.0, it is plausible that the true average of all bags is 2 lbs.
