3. Kuru is a disease of the Fore people of highland New Guinea. It was once transmitted by the consumption of deceased relatives at the mortuary feasts, a ritual that ended by 1960 . Researchers investigated genetic variants that might confer resistance to kuru. The data in the table below are genotypes at codon 129 of the prion protein gene of young and elderly individuals all with the disease. Since the elderly individuals have survived long exposures to kuru, unusually common genotypes in this group might indicate resistant genotypes. Test whether genotype frequencies differ between the two age groups. c. State the hypotheses. d. Calculate the chi-squared and the critical value. e. Calculate the p-value f. Draw the appropriate conclusion.
