The dot plots can be represented by the following sort of data:
Week 1
Week 2
The ranges of week 1 and week 2 are [62, 80] and [62, 89], respectively. Thus, options A and B cannot be true.
The medians are: Week 1 = 72; Week 2 = 73.5. Therefore, the third statement is true.
The means are: Week 1 =72.94; Week 2 = 74.6. This also leads to the fourth statement to be false.
