is the sample mean, and

Answer:
Students on Honor Roll had no advantage to get the Science class requested. It was a fair class assignment. In fact No Honor Roll students had advantage over honor Roll Students in obtaining Science Class as requested.
Step-by-step explanation:
Here let us streamline the information we are given one by one
1.) Honor Roll
Get Requested Science Class : 64
Did Not get Requested Science Class : 80
Total : 144
Percentage of Honor Roll Students getting Science class as requested =
= 44.44%
2.) No Honor Roll
Get Requested Science Class : 315
Did Not get Requested Science Class : 41
Total : 356
Percentage of Non Honor Roll Students getting Science class as requested
= 88.8%
By observing the above result , we can assume that Honor Roll students did not have any advantage over non Honor Roll students in getting Science Class as they requested.
