If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed within $45 of the mean for that year? The mean was 548.30. the SD was 23.85. I know I need to find 2 z-scores, do I divide +45/sd and -45/sd or another methods to find z-scores, then where do I go from there? Formulas are helpful, I need to get to probability as my answer. Thanks for all your help!
