Test the claim that men have a higher rate of red/green color blindness. (Note: Type "p_m" for the symbol pm , for example p_m not = p_w for the proportions are not equal, p_m > p_w for the proportion of men with color blindness is larger, p_m < p_w , for the proportion of men is smaller. ) (a) State the null hypothesis: P_m=p_w (b) State the alternative hypothesis: P_m>p_w (c) The test statistic is [j (d) Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness than women? Use a 5 % significance level. 0 A. Yes OB.No (e) Construct the 95 % confidence interval for the difference between the color blindness rates of men and women.
