Answer:
62.5
Step-by-step explanation:
P = (6.50f) - 100
All you have to do is plug in 25 for f in the equation and solve for P.
P = (6.50*25) - 100
P = 162.5 - 100
P = 62.5

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)
