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:
Step-by-step explanation:
Draw a diagram to illustrate the problem as shown below.
When the smaller gear rotates through a revolution, it sweeps an arc length of
2π(4) = 8π inches.
Part 1
The same arc length is swept by the larger gear. The central angle of the larger gear, x, is
7x = 8π
x = (8π)/7 radians = (8π)/7 * (180/π) = 205.7°
Answer: 205.7° (nearest tenth)
Part 2
When the larger gear makes one rotation, it sweeps an arc length of
2π(7) = 14π inches.
If the central angle for the smaller gear is y radians, then
4y = 14π
y = 3.5π radians = (3.5π)/2π revolutions = 1.75 revolutions
Answer:
The smaller gear makes 1.75 rotations
The constant is 6 as there are 6x when there is 1 Y
