Find the 0 6 quantile of the standard normal distribution answer: We don't have a formula for the cdf, so we use the R 'quantile function' qnorm q0

This is not true for arbitrary random variables: ordinarily, the mean and the variance do not completely determine the distribution, but for a normal random

standard normal distribution, which has mean 0 and variance 1, will be used to determine probabilities of the general normal distribution

The variance can also be calculated using an alternative formula: Why would we use this equation instead? V (x) = ? 2 =
