Problema Solution
In a set of 24 months of data for medical leave that has a mean of
12 days per month and a standard deviation of 4.52,
how many months are expected to have fewer than 16.52
days per month reported medical leave (one standard deviation above the mean)?
Answer provided by our tutors
z=(16.52-12)/4.52
z = 1
P(z<1)=0.8413
Number of months expected to have fewer than 16.52 days per month reported medical leave is 0.8413*24 = 20 months.
