Math Problem Statement
A hospital wants to determine the appropriate dosage of a medication for a certain condition. The effectiveness of the medication is known to follow a normal distribution with a mean dosage of 150 mg and a standard deviation of 20 mg. What percentage of patients should receive a dosage between 130 mg and 170 mg for the medication to be effective?
