(a)
For male:
Answer: (14.37, 19.14)
For female:
Answer: (9.07, 12.43)
(B)
The probability that 95% confidence interval does not contain true population mean is 1 - 0.95 = 0.05
Since both intervals are independent so the probability that both intervals does not contain true parameter is 0.05*0.05 = 0.0025
Answer: 0.0025
(C)
The confidence interval for male has all values above the confidence interval of female. That is lower limit for confidence interval of male is above the upper limit of confidence interval of female. So we can say that males consume more alcohol per week in comparison to female.
Correct option is B.

The effect of exposure to high levels of alcohol consumption was compared to occasional or no alcohol consumption among adult males and females. It is hypothesized that high levels of alcohol consumption is associated with myocardial infarction (MI). This association was studied with 596 incident cases of MI diagnosed in the emergency rooms of several hospitals and compared to 1012 other subjects who visited the same emergency rooms for reasons other than cardiovascular and respiratory diseases. All subjects were asked...
