Question

A researcher selects a sample of 16 women and asks them to rate how important a sense of humor is in someone they want a long-term relationship with.She records scores averaging 1.6 ± 0.8 (M ± SD)on a rating scale from -3 (not important at all)to +3 (very important).Assuming that an average score of 0 is the null hypothesis,test whether or not women find this trait important at a .05 level of significance.
A) Women found this trait to be important, and this result was significant, t(16) = 8.00, p < .05.
B) Women found this trait to be important, and this result was significant, t(15) = 8.00, p < .05.
C) Women did not find this trait to be important, p > .05.
D) There is not enough information to answer this question.

The correct answer is B because the t-test calculation for significance involves the sample size minus one (n-1), which in this case is 15 (16-1). The given average score of 1.6 significantly differs from the null hypothesis average of 0, indicating that women find a sense of humor important in a long-term relationship partner. The calculation details provided (t(15) = 8.00, p < .05) support this conclusion.
