Question

5 from unit 3, lesson 13
the depth of two lakes is measured at multiple spots. for the first lake, the mean depth is
about 45 feet with a standard deviation of eight feet. for the second lake, the mean depth
is about 60 feet with a standard deviation of 27 feet.
noah says the second lake is generally deeper than the first lake. do you agree with noah?

Explanation:

The mean depth represents the average depth of a lake. The second lake has a higher mean depth (60 feet) than the first lake (45 feet). Even though the second lake has a larger standard deviation (more variability in depth), the mean still indicates that, on average, the second lake is deeper. Thus, Noah's statement is correct.

Answer:

Yes, I agree with Noah. The second lake has a higher mean depth, so it is generally deeper.
