Mary and Jane both took PSY230 last semester but they were in two different sections taught by different professors. Mary's class had a mean grade of 85 points with a standard deviation of 5 points while Jane's class had a mean grade of 80 points with a standard deviation of 10 points. Both Mary and Jane earned 88 points. Who did better in class

hope this !

let me know

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
