Question

The table shows summary statistics for the lengths of time students in two different classes took to complete a test.

Class 1 Median time: 37 min Range: 8 min
Class 2 Median time: 45 min Range: 4 min
Which conclusion is true?

Students in Class 1 took more time to complete the test than students in Class 2, and their times were less variable.

Students in Class 1 took more time to complete the test than students in Class 2, and their times were more variable.

Students in Class 1 took less time to complete the test than students in Class 2, and their times were more variable.

Students in Class 1 took less time to complete the test than students in Class 2, and their times were less variable.

2 Answer

  • Ok so the answer isĀ Students in Class 1 took less time to complete the test than students in Class 2, and their times were more variable. Im 10000% positive
  • 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
