Answer: (0.066,0.116)
Step-by-step explanation:
The confidence interval for proportion is given by :-
Given : The proportion of men have red/green color blindness = 
The proportion of women have red/green color blindness = 
Significance level : 
Critical value : 
Now, the 99% confidence interval for the difference between the color blindness rates of men and women will be:-
Hence, the 99% confidence interval for the difference between the color blindness rates of men and women= (0.066,0.116)
Answer:
a. 1/2
b. 1 hair cut
c. 2.5
Step-by-step explanation:
4/8 divde by 4 to simplify and that gets you 1/2
8/4 is 2 so he does one hair cut every two hours
so you know how many he can do in 2 hours so add it up. It’s going to be 2 people in four hours so it will be half a hair cut in 5 hours
4,9, 36, 49, 121, 144, 196, 225
Answer: n = -25
Step-by-step explanation:
you would need to get N by itself so you would subtract 2n from both sides and that would bring you to n+75=50 and then you would need to subtract 75 from both sides and that leads you to n=-25
