A study is being carried out on the effects of divided attention on driving performance. It involves testing participants on their reaction times to road hazards in a driving simulator. On two-thirds of the trials when a road hazard appears, the participant is already engaged in a secondary task of responding to questions. For a third of trials these are easy simple mental arithmetic questions and in the other third of trials, they are more demanding problem-solving questions . The researchers wish to compare participants' reaction times to spotting the hazard whilst varying the secondary task.What type of ANOVA design will their data analysis use?Question 11Answera.An independent sample mixed model ANOVAb.A repeated-measures one-way ANOVAc.A two-way repeated-measures one way ANOVAd.A 3-way factorial independent sample ANOVA
