A salt company packages salt in 5-pound bags. The amount of salt per bag varies according to a normal distribution which has a mean of 5 lbs and a standard deviation of 0.05 lbs. A sample of 25 bags is selected from the day's production and the mean of the sample is determined. If it is less than 4.98 pounds, the fill per bag will be increased.

What is the probability that this will happen? Draw a graph of the normail distribution and indicate the area of interest.
