A) has an area equal to B) has a mean of 0 and a standard deviation of 1. C) has a mean of 1 and a variance of 0. D) cannot be used to approximate discrete probability distributions. 2) If a particular set of data is approximately normally distributed, we would 2). find that approximately A) 4 of every 5 observations would fall between standard deviations around the mean. B) 19 of every 20 observations would fall between 2 standard deviations around the mean. C) 2 of every 3 observations would fall between 1 standard deviation around the mean. D) All the above. 3) For some value of Z, the value of the cumulative standardized Normal 3). Distribution is The value of Z is A) B) C) D) 4) The value of the cumulative standardized Normal Distribution at Z is 4). The value of Z is A) B) C) D) SHORT ANSWER.
