The dot plot below shows the hourly rate of some babysitters in a city:
a number line is shown from 1 dollar to 5 dollars in increments of 1 dollar for each tick mark. the horizontal axis label is dollar per hour. there are 4 dots above 2 dollars, 2 dots above 3 dollars, 3 dots above 4 dollars, and 1 dot above 5 dollars. the title of the line plot is babysitting rates.
which statement best describes the shape of the data?
it is symmetric and has a peak at $5.00.
it is not symmetric and has a peak at $2.00.
it is a cluster from $1.00 to $5.00 and has gaps.
it is a cluster from $1.00 to $5.00 and has no gaps.
