2. There are an infinite number of normal distributions because there are infinite possible values for [I and 0. There is only one standard normal distribution, however. a. The mean of the standard normal distribution is . and its variance is . Its standard deviation is b. The mean |.l and standard deviation 0' of a normally distributed variable are 75 and 8. How would you transform this variable to yield a normal distribution with mean 0 and standard deviation 1
