Answer:
Option C) Students in Class 1 took less time to complete the test than students in Class 2, and their times were more variable
Step-by-step explanation:
Given that median time of class 1 is 37 and range is 8 minutes
This implies the time has minimum as 33 and maximum as 41.
Median time for class 2 is 45 with range 4 minutes
This implies minimum time for class 2 is 43 and maximum time is 47.
On comparing we find that class 1 took less time to complete the test than students in class 1
But since there is more difference i.e. range is double for class I as that of class II there is more variability in class I than II.
Hence answer is
C Students in Class 1 took less time to complete the test than students in Class 2, and their times were more variable
