The effect it would have on the dot plot graph is that: B. The mean will decrease.

What is the Mean of a Dot Plot?

The mean of a dot plot is found by simply adding up all data points on the dot plot and divide by the number of data points we have on the dot plot.

Mean of the first 10 monologues = (1.5 + 1.5 + 2 + 2.5 + 2.5 + 2.5 + 3 + 3.5 + 3.5 + 4)/10 = 2.65

Mean of the first 10 monologues + 0.5 minutes = (1.5 + 1.5 + 2 + 2.5 + 2.5 + 2.5 + 3 + 3.5 + 3.5 + 4 + 0.5)/11 = 2.45

Therefore, the effect it would have on the dot plot graph is that: B. The mean will decrease.
