If a person bought 1 share of Google stock
within the last year, what is the probability that the stock on that day closed at less than $950 per share. Would this be considered unusual? Use the definition of unusual from the course textbook that is measured as a number of standard deviations. In order find the z-score I’d subtract the mean of 59.3 from $950 and divide the standard deviation. z=(x−μ)/σ, z=(950-59.30)/32.89 = 27.08.
