I'm completing a survey and trying to figure out if I will reject my hypotheses. My professor said I will because -9.13 is less than -2.017. Where'd she get -2.017 from? My survey info is below.

Based on satisfaction, 20% of the sample population gave a four with how satisfied they are with their supervisor. There is a 95% confidence that the population that feels this way will fall between 2.44 and 3.38. The interval min and max are 2.45 and 3.37.
