Researchers tested an isotope in human skeletal tissue from a medieval burial site to determine whether people in medieval times ate seafood regularly. It is believed that bishops and priests had access to seafood during fast days and other holy days, while lay individuals did not. A higher percentage of collagen indicates more seafood in a person's diet. Is there a statistically significant percent increase in the percentage of collagen.in the priests and bishops compared to the lay individuals? % Collagen Priests 7.9 Laypersons 5.4 5.4 Check the assumptions and conditions for inference for a two-sample t-test. Select all that apply. LY A. The Normal population assumption is not met. Not enough information is given to verify the nearly Normal condition. LY B. The independent groups assumption cannot be verified. There is no information given to indicate that the two groups are not related. LY C. The independence assumption is not met. Since the population size is unknown, the 10% condition cannot be verified. D. All assumptions and conditions have been met. Test an appropriate hypothesis and state your conclusion. Assume a = 0.05. Let uy be the population mean for the priests, and J2 be the population mean for the laypersons. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: Hy - 12= 0 B. HO:H1 - H2 = 0 HA : H1 - H2# 0 HA: H1 - H2 >0 O C. HO: H1 - H20 HA: H1 - H2
