Answer:
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 between
that is one standard deviation from mean.
- about 95% data lies between
that is one standard deviation from mean.
- about 99.7% data lies between
that is one standard deviation from mean.
Thus, 99.7% of data will lie between that is it will lie in the range (198,612)
