I was struggling with this statistics problem:

Suppose a research team takes a simple random sample of 100 Parma wallabies. In this sample, the tails of the wallabies have a mean length of 46 centimeters and a standard deviation of 2.6 centimeters.

What percent of the time would you expect a simple random sample of 100 Parma wallabies to have a sample mean that is not in the 95% confidence interval?

5%
