2. For standard normal random variable Z, (i) given p(Z< z0) = 0.1056, find z0-score, (ii) Given p(-z0

3. The random variable X has a normal distribution with mean =50 and the standard deviation = 5.

Find the probability that (i)X exceeds 55, (i)X is between 45 and 57, (iii)X is less than 63, (iv)

X is more than 75.
