Unsure of Hypothesis Test to Use

I am trying to compare whether there is a statistical difference between response rates for a target group and a control group. The literature says to use a one-sided t-test for proportions....I'm assuming to compare whether target response rates are statistically greater than control response rates. I'm also thinking of a two sample t-test for proportions...to test the following null hypothesis: Proportion "Target" - Proportion "Control" = 0. Any ideas?
