What is the name of the statistical test that is used to test differences in some dichotomous dependent variable that is measured at the nominal level of measurement?

You perform a Friedman test when you have one within-subjects independent variable with two or more levels and a dependent variable that is not interval and normally distributed (but at least ordinal). We will use this test to determine if there is a difference in the reading, writing and math scores.

Based on your t test, the difference is statistically significant. Calculating the difference as a percent change only changes the way you are looking at it, not the outcome of the test — it is still statistically significant.
