Step-by-step explanation:

From the question we are told that

     The  population mean  is  

      The standard deviation is  

We also told in the question that the birth weight is  approximately Normally distributed

    i.e      

Given that Low-birth-weight babies weighing less than 2500 grams,then the proportion of babies born full term are low-birth-weight babies is mathematically represented as

Generally  

So

substituting values

Now from the standardized normal distribution table(These value can also be obtained from Calculator dot com) the value of

=>    

Given that  very-low-birth-weight babies (weighing less than 1500 grams,then the  proportion of babies born full term are very-low-birth-weight babies is mathematically represented as

substituting values

Now from the standardized normal distribution table(These value can also be obtained from calculator dot com) the value of
