Humerus bones from the same species of animal tend to have approximately the same length-to-width ratios. When fossils of humerus bones are discovered, archaeologists can often determin species of animal by examining the length-to-width ratios of the bones. It is known that species A exhibits a mean ratio of 8.3. Suppose 41 fossils of humerus bones were unearthed at an archaeological site, where species A is believed to have lived. The length-to-width ratios of the bones are listed in the accompanying table. Complete parts a and b. Click the icon to view the table. a. Test whether the population mean ratio of all bones of this particular species differs from 8.3. Use a = 0.01. State the null and alternative hypotheses. Choose the correct answer below O A. Ho: H = 8.3 O B. Ho: H = 8.3 Ha: H# 8.3 Ha: H 8.3 If a = 0.01, find the rejection region for the test. Choose the correct answer below. O A. Z 2.33 O C. z 2.575 O E. z> 2.575 or z 2.33 or z
