Problem PageQuestion Calcium levels in people are normally distributed with a mean of mg/dL and a standard deviation of mg/dL. Individuals with calcium levels in the bottom of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.

The  calcium level that is the borderline between low calcium levels and those not considered low is  

Step-by-step explanation:

From the question we are told that

    The mean is  

     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

  Since the calcium level is normally distributed the z-value is  evaluated as

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

=>    

substituting values

=>    

=>
