Question

I need help with this because I feel like it C

Answer 1

The dot plots can be represented by the following sort of data:

Week 1

`\mleft\lbrace62,68,68,68,69,70,70,72,72,72,75,75,76,78,78,80,80,80\mright\rbrace`

Week 2

`\begin{gathered} \mleft\lbrace62,62,64,64,64,65,68,68,68,69,70,70,72,72,72,75,75,76,78,78,\ldots\mright? \\ \ldots80,80,80,85,85,86,86,86,89,89\} \end{gathered}`

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.
