1) Basic Computations: Given that x is a normal variable with mean (u) = 110 and standard deviation (o) =12, find:
P(x≤ 120)
P(x≥ 80)
P(108 ≤ x ≤ 117)
2) Find the area to the left of 2 on a standard normal distribution
3) Find the area to the left of -1 on a standard normal distribution
4) Find the area to the left of -1 and 2 on a standard normal distribution
5) find the area to the right of 2 on a standard normal distribution
6) find the area to the left of 40 on a normal distribution with a mean of 50 and standard deviation of 8
7) Find the area to the left of 55 on a normal distribution with a mean of 50 and a standard deviation of 8
8) find the area between 40 and 55 on a normal distribution with a mean of 50 and standard deviation of 8
