a) Using formula , the z-value corresponds to x= 900 will be :
Now, by using the standard normal z-table , the probability demand will exceed 900 units in a month :-
Hence, the probability demand will exceed 900 units in a month=0.1587
a) Using formula , the z-value corresponds to x= 392 will be :
Now, by using the standard normal z-table , the probability demand will be less than 392 units in a month :-
Hence, the probability demand will be less than 392 units in a month = 0.0618
