Question 11 The study design is best described as a ... O Three-way mixed design. O Two-way repeated measures design. O Three-way independent design. Four-way mixed design. O Three-way repeated measures design.Question 15 What R code should the researcher use to fit a model that tests the researchers hypotheses? O afex: : aov_4(arousal ~ time + imagery + group (time*imagerylid), data = imagery_tib) O afex: : dov_4(arousal ~ time* imagery*group + (time*imagerylid), data = imagery_tib) O afex: : dov_4(arousal ~ time*imagery*group + (1lid), data = imagery_tib) O afex: : dov_4(arousal ~ time + imagery + group + (1lid), data = imagery_tib) O afex: : dov_4(arousal ~ imagery*group + (timelid), data = imagery_tib)Scenario 2 An experiment was done to look in the positive arousing effects of imagery on different people. A sample of statistics lecturers was compared against a group of students, Both groups received presentations of positive images jog. cats and burning), neutral images feg duvets and lightbulbet, and negative images jog corpses and vivisoution photographed. Their emotional arousal was mansured physiologically farger values indicate higher emotional around; both before and after each batch of images (time). The onder in which participants saw the batches of positive. poutsal and negative mages was randomised to avoid onour mnecta It was hypothesised that positive images would increase emotional grows, negative images would reduce arousal and that neutral imaged would have no effect. These effects wore hypothesiand to comparable across the participant groups lecturers and studental. The questions in this soation relate to this mooarch scenario Question 11 1 pts The study design is best desonbad as a .. O Three way niand design.
