The standard deviation 
The proportion of the population with low calcium level is
5% = 0.05
Let X be a X random calcium level
Now the P(X < c) = 0.05
Here P denotes probability
c is population with calcium level at the borderline

The critical value for 0.05 from the standard normal distribution table is

=> 
substituting values

=> 
=>
