The correct option is B.
Thus, 68% percentage of the balls weigh within one standard deviation of the mean.
<h3>What is the empirical formula rule?</h3>
The Empirical Rule indicates that 99.7% of data that are observed to have a normal distribution fall within 3 standard deviations of the mean. According to this formula, 68 percent of the data are within one standard deviation, 95 percent are within two standard deviations, and 99.7 percent are within three standard deviations of the mean.
<h3>According to the empirical formula rule:</h3>

There was 32 total pupils and 2 obtained a level 5, so you subtract 2 from 32 and get 30. Then you divide 30 by 5 because to give you the the number of students which got a level 4 which is 6. 6+2=8 32-8=24
Level 4; 6pupils
Level 3; 24
Level 5:2
