Question
The correct conclusion is that we conclude that the average length of stay of all surgeries of this type days.
What level of concern do you have for the validity of your results?
Low our
Moderate
the original data is not normally distributed which is an assumptions violation
Extreme
we should not use any part of what we've done to make a conclusion
None
our sample size is larger than 30 so there should be no problem with the conclusion
