(2 pts) In a study of red/green color blindness, 700 men and
2150 women are randomly selected and tested. Among the men, 64 have
red/green color blindness. Among the women, 6 have red/green color
blindness. 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_mnot=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:
(b) State the alternative hypothesis:
Note that computation of the test statistic will produce z = 13.16
(c) Is there sufficient evidence to support the claim that men
have a higher rate of red/green color blindness than women? Use a
10 % significance level.
A. Yes
B. No
a)
H0 : pm= pw
b)
Ha: pm > pw
c)
Here, z = 13.16 is given
p value = 0.0001
yes because p value < 0.10

Color Blindness in Men and Women: In a study of red/green color blindness, 500 men and 2100 women are randomly selected and tested. Among the men, 45 have a red/green color blindness. Among the women, 6 have a red/green color blindness. Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness that women?
