Problem 1 A skewed standard normal distribution is defined as f(x) = 20(x)(m) where (x) is the standard normal probability density function, (x) is the standard normal cumulative distribution function, and is the skewness parameter. You can use the Excel function Normdist for both the PDF and CDF. A standard normal distribution has a mean of 0 and a standard deviation of 1. Write a code to compute the probability that a randomly selected x falls between two user-provided numbers A and B where A
