A researcher was interested in stress levels of lecturers during lectures. She took the same group of 8 lecturers and measured their anxiety (out of 15) during a normal lecture and again in a lecture in which she had paid students to be disruptive and misbehave. Based on the SPSS output, how would you interpret these results? Indicate your answer in APA format. (3 pts) Paired Samples Test Paired Differences Mean Pair 1 Misbehaved - Normal Lecture 6.2500 Std.

In the SPSS output below you will find output for the difference between means for 'Liking Metal Music' and 'Social Isolation' by Age Group (Group 1: 13-15 years of age; Group 2: 16-19 years of age). The data is taken from a random sample of teenagers and 'Liking Metal Music' and 'Social Isolation' are both measured on a continuous scale, where higher values indicate more of the trait. Use your knowledge and the information below to do the following (4 pts): a. Write plausible research hypotheses about the relationship between the grouping variable (Age Group) and each of the dependent variables (two models). b. State the null hypothesis for both models. c. Using the results below, test both of the null hypotheses and make a decision on each one, reporting the information you used to make that decision. Interpret your results for both of your hypotheses in APA format
