I've been tasked with determining who the easiest and harshest professors are based on their grades. Provide a query that can tell me the min and max grades assigned by each professor. However, as a significant number of students fail their classes unrelated to the professor, please excuse all grades of 0.0 from the statistics. Also, please exclude professors with one or less passing students. There are two tables: the table "students" records the name, grade, and course for each student, the table "profs" records the name and course that each professor teaches. You may assume that there are no NULL values and each professor has a unique name. Here is some example data: Table: students grade name course Zizhen Cam 4.0 450 Table: profs 3.5 480 name course Cam 3.0 450 Josh 480 Jie 0.0 231 Josh 450 Jie 2.0 331 Rich 231 Anne 3.0 231 Sebnem 331 Josh 1.0 231 Josh 0.0 480 Josh 0.0 331 And the desired results for this example data (exact column names and row order doesn't matter): min max name Josh 3.0 4.0 Rich 1.0 3.0

I've been tasked with determining who the easiest and harshest professors are based on
their grades. Provide a query that can tell me the min and max grades assigned by each
professor. However, as a significant number of students fail their classes unrelated to
the professor, please excuse all grades of 0.0 from the statistics. Also, please exclude
professors with one or less passing students. There are two tables: the table "students"
records the name, grade, and course for each student, the table "profs" records the name
and course that each professor teaches. You may assume that there are no NULL values
and each professor has a unique name. Here is some example data:
Table: students
name
grade
course
Zizhen
4.0

Table: profs
Cam
3.5
480
name

Cam

And the desired results for this example data (exact column names and row order doesn't
matter):
