198 and 612
Step-by-step explanation:
We are given that the scores are normally distributed.
The mean of the data is 405.
The standard deviation of this data is 69.
Empirical rule states that for a normally distributed data that
about 68% data lies betweenThus, 99.7% of data will lie between
that is it will lie in the range (198,612)
