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:
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
The population proportion have the following distribution
And we can solve the problem using the z score on this case given by:
We are interested on this probability:
And we can use the z score formula, and we got this:
And we can find this probability like this:
