Tomas creates this dot plot. Which two numbers in the dot plot appear in his dataset the same number of times? List the lower number first and the higher number second. (This is my rough recreation of the picture,2 dots on 75,4 dots on 76,4 dots on 77,0 dots on 78 and 3 dots on 79)

The numbers 76 and 77 both appear in the dataset 4 times.
