You have been commissioned to study the difference in expected sick leave among men and women in a particular organization. You know from previous studies that it is reasonable to consider sick leave measured in number of days per year in the two groups as normally distributed and that the standard deviation can be assumed to be equal in both groups. The survey is done so that a random sample of 18 men and 11 women are taken out, after which these people's sick leave is examined. In the group of men, the mean value for sick leave was 10.9 and the standard deviation was 5.3 days per year. Among women, the mean value was 9.1 and the standard deviation 5.2 days
You have been commissioned to study the difference in expected sick leave
among men and women in a particular organization. You know from previous studies that it is reasonable to consider sick leave measured in
number of days per year in the two groups as
the standard deviation can be assumed to be equal in both groups.
The survey is done so that a random sample of 18 men and
11 women are taken out, after which these people's sick leave is examined.
In the group of men, the
Among women, the mean value was 9.1 and the standard deviation 5.2 days per year.
Determine a confidence interval with a confidence level of 99% for the difference between the two groups' expected sick leave. Enter the upper
limit of this
use women's sick leave as the first term in the difference calculated between the two groups.
