Answer:
Students who studied got following marks =
<em>88,90,86,96</em>
Mean = <em>(88 + 90 + 86 + 96)/4 = 90</em> and mean absolute deviation = <em>3</em>
Students who did not study got following marks =
<em>34,67,80,59</em>
Mean = <em>(34 + 67 + 80 + 59)/4 = 60</em> and mean absolute deviation = <em>13.5</em>
The correct statements are :
The mean absolute deviation for the group of students who did not study is <u><em>13.5</em></u><u>.</u>
The data for the group that did not study is more spread out than the data for the group that studied
The data for the group that studied is more are more clustered around the mean than the data for the group that did not study.
