The line plot shows the result of a survey of two groups of customers on how many portable electronic devices they have in their household.

which conclusion can be drawn about the data sets?

the median for group 1 and group 2 is about the same.

the range for group 2 is greater than the range for group 1.

the mode is the same for both sets of data.

on average, the people in group 1 and in group 2 have about 5 electronic devices in their household.

I would think that the medians are very close together. Because in group 1, the median was 4.5 while in group 2 the median was 5 so I would say that is pretty close. "The range for group 2 is greater than the range of group 1" is not correct because in group 1 there is an x on 1 and an x on 10 while at group 2, there is a 2 x's on 2 and 2 x's on 8. "The mode is the same for both sets of data" is not correct because in group 1 there was 3 x's on 3,4,and 7 while in group 2 there was 3 x's on 3 and 4 x's on 6. "On average, the people in group 1 and in group 2 have about 5 electronic devices in their household" is not correct either because in group 1 there was 2 x's on 5 while in group 2 there was 1 x on 5 so this wouldn't be correct. I am sorry for how long this turned out but I hope this helped you!  

She should use 12/3 to measure
