41 fossil humerus bones were dug at a site where Species A is known to have existed. Species A is known to have a mean ratio of 8.5. (Assume that all bones are from the same species.) The length-to-width ratios of these humerus bones has sample mean 9.26 and sample standard deviation 1.20. Can we conclude that these bones belong to Species A?

Perform a level 0.05 test to check.
