A score of 85 would be 1 standard deviation from the mean, 74. Using the 68-95-99.7 rule, we know that 68% of normally distributed data falls within 1 standard deviation of the mean. This means that 100%-68% = 32% of the data is either higher or lower. 32/2 = 16% of the data will be higher than 1 standard deviation from the mean and 16% of the data will be lower than 1 standard deviation from the mean. This means that 16% of the graduating seniors should have a score above 85%.

Step-by-step explanation:
If you multiply a number then it becomes grater.
So you are multiplying 9.73 x 103 in the second statement.
The answer then is that since the 97.3 in the first section is the same number as the 97.3 in the second part.
