Problem 6 (39 points): Color blindness is a condition much more prevalent among males than females. But is color blindness uniformly spread among males? Let Pz be the proportion of color-blind people in the Asian American male population. In a random sample of 10 Caucasian American males, 65 are diagnosed with color blindness. In a random sample of 792 Asian American males, 43 are diagnosed with color blindness. Do the sample results show good evidence that the true population proportion of color-blind Caucasian American males is greater than the population proportion among Asian American males?
1. The null hypothesis is Ho: P-P=0. What is the alternative hypothesis? Ha:
2. Calculate the individual sample proportions and the sample statistic to three decimal places: pm, Pa, P-p.
3. Here is a plot of a randomization distribution from 3000 randomization samples. Is it appropriate to use this distribution for p-value estimation? Why or why not?
4. What is the p-value for the test according to the above plot? p-value =
5. Fill in the blanks in the following interpretation of the p-value. Assuming that there is no difference (choose one) in the proportions of color-blind Caucasian American and Asian American males, the chance of observing a statistic as extreme as ours is equal to.
