The two dot 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 for the first mark, there is 1 dot above the second mark, there is 1 dot above the third mark, there is 1 dot above the fourth mark and there are two dots 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 1.7. approximately how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders? (round all values to the tenths place.) 1.2 1.4 2.4 2.8

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
