On a recent blood tesr an individual had a hemaocrit reading of 42.6 and the 95% limits for the hematocrit reading are 36.0 and 50.0 a.)What is the mean hematocrit level if those are the limits? b.) Should the individual be concerned about the reading found?

It appears the mean would be 43.0 for (a) and (b) I would not be concerned since the person is only off the mean by -0.4.
