Answer:
It is more reasonable to model the standard class with normal distribution
Step-by-step explanation:
- Standard Class:
The range of grades/marks obtained seems normally distributed with a reasonable average of 65% and covering the entire spectrum. Since most of the students score around average 65% the bump of normal bell curve is well situated about the mean.
- Advanced Class:
The range of grades/marks obtained seems concentrated at around 2 means one for the students with higher ability of mathematics and one for the students with lower ability of mathematics ( Higher for english ). The mathematics abled score in the upper percentile while the English abled score in the mid-lower percentile. The deviation of average scores for is large enough to make this a bimodal distribution rather than a normal distribution. However, there's strong correlation between excelling in one academic subject and excelling in another.
Conclusion:
It is more reasonable to model the standard class with normal distribution
