A researcher thinks that how often someone reports visiting a science museum in a year is different for people with children and people with at least one child. They get the following output: Group Statistics Std. Std. Error Respondent's children Visits to No children N 797 Mean Deviation Mean 0.27 1.077 0.038 science museum 1 or more children 2062 1.65 4.997 0.969 Independent Samples Test Levene's Test for Equality of Variances t-test for Equality of Means F Visits to Equal 4.492 Sig. 0.034 -1.231 t df 2857 Sig.

(note how the problem is worded to indicate if it is one or two tailed)
