Suppose you are examining a random variable Y that is normally distributed. You transform it into a standard normal random variable. One particular point of y=16.5 yields a z-score of z=-1.64. If the standard deviation of Y is 2.97, what is the mean of Ý, accurate to two decimal places? 22.54 3.42 O 11.63 O -24.09 21.37
