The pulse rates, in beats per minute, for some students of a class are shown below:

82, 88, 67, 88, 85, 67, 79, 76, 79, 67, 88, 67, 85, 79, 67, 88, 79, 88, 76, 67

midge created the following incorrect dot plot to represent the data:

dot plot showing 6 dots over 67, 2 dots over 76, 3 dots over 79, 1 dot over 82, 2 dots over 85, and 5 dots over 88

what should midge do to make the dot plot correct?

put another dot on 79
put another dot on 76
delete one dot on 88
delete one dot on 67
