4. The Bureau of Labor Statistics would like an estimate of the average age of workers in a particular field. 50 people are sampled and their ages are recorded.

The 95% Confidence Interval is calculated as being (33.0, 39.8) What is the correct interpretation of this Confidence Interval?

A. The true average age of workers will fall between 33.0 and 39.8

B. 95% of all people in this field are between 33 and 39.8 years old.

C. If 100 samples are taken of this population using this same method and then the

Confidence Interval of each are calculated, about 95 of the intervals will contain the true population mean value.

D. There is a 95% probability that the true average is between 33 and 39.8
