         A group of researchers wants to determine if Caucasians and African-Americans are equally likely to inherit cystic fibrosis (CF). They collect data on cystic fibrosis (yes/no) and calculate frequencies for each group. They collected data from 820 people overall. They observed the following frequencies: White-YesCF (80), White-NoCF (430), Black-YesCF (16), Black-NoCF (294). Use a two-variable chi-square analysis (where α = .01) to determine if there are significant differences in cystic fibrosis by race.

        7.      Identify the null hypothesis

        8.      List your degrees of freedom

        9.      List the expected frequency (raw number) for White patients with cystic fibrosis
