A statistics instructor randomly selected four bags of oranges, each bag labeled 10 pounds, and weighed the bags. They weighed

9.2,

9.4,

9.7,

and

9.4

pounds.

Assume that the distribution of weights is Normal. Find a 95% confidence interval for the mean weight of all bags of oranges. Use technology for your calculations. Answer parts a and b below.

a. Choose the correct interpretation of the confidence interval below and, if necessary, fill in the answer boxes to complete your choice.

There is a 95% chance that all intervals will be between

nothing

and

nothing.

We are 95% confident the population mean is between

nothing

and

nothing.

We are 95% confident that the sample mean is between

nothing

and

nothing.

The requirements for constructing a confidence interval are not satisfied.
