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)
First, let's only the expression with x stay on the let side: let's add 9 to both sides of the equation.

which is

now, let's multiply everything by 2:


so the answer is -32!
