A Researcher Has Participants Rate the Likability of a Sexually

A researcher has participants rate the likability of a sexually promiscuous person described in a vignette as being male (n = 20) or female (n = 12) .The mean likability ratings in each group were 4.0.If the null hypothesis is that there is no difference in likability ratings,then do likability ratings differ at a .05 level of significance?

A) Yes, this result is significant, p < .05.
B) No, this result is not significant, t(30) = 0.
C) No, this result is not significant, t(30) = 1.00.
D) There is not enough information to answer this question because the variance in each sample is not given.
