1. A researcher selects a sample of 19 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 on a rating scale from -3 (not important at all) to +3 (very important). The mean score in her sample is 1.8 and the standard deviation is 0.6. 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.
