A researcher studies whether negative political campaign advertisements cause people to report being more or less likely to vote for the candidate targeted in the ad (-3 = less likely to vote for candidate, 0 = did not change opinion, 3 = more likely to vote for candidate). They find a mean in their sample of M = -2.2 and compare it to μ = 0. Using a two-tailed α = .01, they conduct a one-sample t-test. They find that p = .042. What is their substantive conclusion?   A) The ad makes people less likely to vote for the candidate   B) People do not report being any more or less likely to vote for the candidate after seeing the ad   C) The ad makes people more likely to vote for the candidate   D) Cannot determine from information given
