Do the chi-square test to see if the numbers are random at a 0.05 level of significance.

Value 1 2 3 4 5
Observed 110 80 90 100 120
Expected 100 100 100 100 100


The test value d(4,0.05) = 9.488.



Since 10.0 is greater than 9.488 the numbers are not random. However, it is very close. At higher level of significance they would be random.
