Question:
Given a normal distribution with = 50 and = 4, calculate the probability that:
- X > 43
- X < 42
- X > 57.5
- 42 < x < 48
- X < 40 or X > 55
- 5% of the values are less than what X value
- 60% of the values are between what two X values ( symmetrically distributed about the mean )
- 85% of the values will be above what X value.
