Which of the following statements is true about the sample? It is not a valid sample because it is only a short study. It is a valid sample because money was offered to participants. It is a valid sample because the first 10 people were selected to participate. It is not a valid sample because it is not a random sample of the population.

    The two plots below show the heights of some sixth graders and some seventh graders: Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the second mark, 3 dots above the third mark, 1 dot above the fourth mark and 1 dot above the sixth mark. The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 1.0. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)
