Scenario 1: A researcher suspects that increasing the level of lighting during the winter months will have a positive effect on people moods. To test this hypothesis, the researcher identifies a sample of n = 36 college students living on one floor of a dormitory. Each student is given a mood questionnaire at the beginning of February, and then all the lights on the dormitory floor are changed from 75-watt to 100-watt bulbs. After 4 weeks, the researcher again measures each student’s mood and records the amount of difference between the two measurements.  Using α = .05, the researcher wants to know whether the lighting significantly increased the student’s good moods.   Fill out the answer by writing in the following: Be sure to show work for degrees of freedom Type of t-test:        H0:     H1:     Degrees of freedom (df):
