Using the 68-95-99.7 rule, given the average test score of 83 and a standard deviation of 10, what is the range of scores in the 68th percentile? A. 63-103 B. 46-66 C. 53-113 D. 73-93

Step 1
The 68-95-99.7 rule states that for a normal distribution: - 68% of the data falls within 1 standard deviation of the mean - 95% of the data falls within 2 standard deviations of the mean - 99.7% of the data falls within 3 standard deviations of the mean Show more…
