distribution (interpolate, as neded)
0.668
b) Converting a normal probability to a standard normal probability.
Given that X has the normal distribution N (60,4), Find P{55SX363}.
) Let X have a binomial distribution with p 0.4 and n150.
Approximate the probability that:
1) X is between 52 and 71 both inclusive.
2) X is greater than 67.
3) Calculate the Mean and Standard Deviation of X.
