Question
As per empirical rule area under the curve for z value varying from -3 to +3 is________Group of answer choices100%99.7%68%95%Next
Solution
The answer is 99.7%. This is based on the empirical rule, also known as the 68-95-99.7 rule, which states that for a normal distribution, 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations. Therefore, the area under the curve for a z value (standard score) varying from -3 to +3 is 99.7%.
