I have given a take home assignment to test whether sample means taken
from two independent populations are same, the population means and
population variances are unknown. what would be the test statistic for
that test?
And in case of the two populations are dependent can i use the same
test statistic?

I'm curious why you recommended the chi-squared test for homogeneity.
As far as I'm aware, it applies to categorical data, not numeric data
that the OP is trying to analyze.
