Helen gathered data on the fuel efficiency of compact sedans. Her sample contains 80 data points, and the standard error of the mean is approximately 0.595. What is the standard deviation? Round your answer to the nearest hundredth.

5.32

Step-by-step explanation:

It took me a while to figure this out myself, here is how I found the

The question gives sample number(80) and the standard error(0.595).

To get the standard error number they use this equation:

So to find the standard deviation, take and times it by the standard error to get the answer.

x 0.595 = 5.321841786449499

And then round to the nearest hundredth: 5.32

- 5.32
