7. Kuru is a prion disease of the Fore people of highland New Guinea and is similar to CreutzfeldtJakob disease. It was once transmitted by the consumption of deceased relatives (yes, this is cannibalism) at mortuary feasts, a ritual that was ended in the 1960s. Using archived tissue samples, a group of researchers investigated genetic variants that might confer resistance to kuru. The data in the following table are genotypes at codon 129 of the prior protein gene of young and elderly individuals who all had Kuru disease. Since the elderly individuals have survived long exposure to Kuru, unusually common genotypes in this group might indicated resistant genotypes. a. Select an appropriate statistical test, and briefly justify your choice b. Specify the statistical hypotheses Ho: The proportion of deaths is same for all types of windows. i.e. \( =1 / 3 \) Ha: Some of the population proportions differ from the values stated in the null hypothesis. c. List the assumptions, if any, of your chosen statistical test. If appropriate, check how well the data fit these assumptions (attach and label any necessary output). d. Perform your test and write an appropriate summary statement. Include the appropriate output from the test that you performed.
