Dr. m hypothesizes that participants who spend time in a hot room will have worse moods than participants who spend time in a normal room. Participants were randomly assigned to spend 15 minutes in either a 95 degree room (experimental group; N1 = 14) or a 72 degree room (control group; N2 = 14). Afterwards they completed a mood measure. Scores could range from 1-20, with higher scores indicating a better mood. Experimental (hot room) group:1 = 13.61 81 = 1.90 Control (normal room) group: 2 = 15.20 82 = 2.20 Answer Questions below 1. STEP 1: Identify your null and alternative hypotheses. H0: HA: 2.Directional or non-directional hypothesis? 3. 4. 8. One- or two-tailed test? What is the anlue (see page 433) given your degrees of freedom (N11) + (N21)? 5. Calculate your m. 6. 7. Is the probability of getting your W by chance alone greater Will you reject or fail to reject the null hypothesis? Why? than or less than .05? What conclusion can you make regarding the research queson? (Say if there i_s or is not a significant difference between groups. If there is, say which group had the worse mood.)
