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 sample size is near 30, so while that's likely sufficient for to be approximately normally distributed, seeing that the original data isn't extremely skewed would make us feel more comfortable

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
