Can you help me understand this Mathematics question?

• Mr. Jones and the New Worksheet

Mr. Jones wanted to check if there was an observable impact of a particular worksheet on his students’ test scores for Chapter 1.His idea was to test if there was a significant variation in the average test score of the class that used the worksheet in comparison to the class that did not.In the class before lunch, he used the worksheet but not the class after lunch.He has 23 students in each of the two classes.Their test scores are below:

 Before Lunch After Lunch 86 79 23 67 59 45 74 46 98 67 38 90 81 80 14 79 32 72 38 63 35 84 51 38 31 60 18 56 57 20 44 70 68 43 27 33 24 16 16 14 31 58 24 30 82 95
