An education policy researcher had a random sample of 100 elementary grade 6 students

from Manitoba and Ontario to test their math level. The average grade in Manitoba is 66,

and the standard deviation is 10; while the average grade in Ontario is 70, and the

3standard deviation of the scores is 12. Can you make the conclusion that Ontario

students have higher math skills than students from Manitoba based on the results, why?
