Calculate average from a given set of keys and values

Hello,
I am writing a script which expects as its input a hash with student names as the keys and marks as the values. The script then returns array of average marks for student scored 60-70, 70-80, and over 90.

Output expected

The test script so far I have written looks like this

I am able to store the input as hash with keys and its values but not able to calculate the average and give the output as expected. Any suggestions would be appreciated.

thank you

Change for students to for student then you can continue writing script to calculate averages.

The script posted and output don't show any average calculation. Grades range total maybe.
