A sample of 22 African Martial Eagles (the largest eagle in Africa) have a wingspan of 2.6 meters with a standard deviation of 28.9 cm. The population standard deviation is 20.8 cm. Do the sample data provide convincing evidence to support the claim that the wingspans are different from the population standard deviation? Test the hypothesis using a 10% level of significance.

Question
A sample of 22 African Martial Eagles (the largest eagle in Africa) have a wingspan of 2.6 meters with a
standard deviation of 28.9 cm. The population standard deviation is 20.8 cm. Do the sample data provide
convincing evidence to support the claim that the wingspans are different from the population standard
deviation? Test the hypothesis using a 10% level of significance.
What are the correct hypotheses? (Select the correct symbols and use
decimal values not percentages.)
