A researcher with the Ministry of Transportation is commissioned to study the drive times towork (one-way) for U.S. cities. The underlying hypothesis is that average commute times aredifferent across cities, To test the hypothesis, the researcher randomly selects six people fromeach of the four cities and records their one-way commute times to work. Refer to the belowdata on one-way commute times (in minutes) to work. Note that the grand mean is 36.625.HoustonCharlotte25Tucson25Akron4510151053519155510301050703524:3331074.16736.66710.833524167436.6673216714.167Which of the following is the mean square for treatments?A. 18,567.63B. 13,281.79C. 5,285.83D. 4,427.26

Describe a study in which you can use both nonparametric and parametric statistics. A researcher has participants expecting to receive either painful or mild electrical shocks during a study wait in a quarter-full waiting room with other participants.

Design a two-factor ANOVA with variables of interest (personal, academic, career). In addition state your 3 hypothesis (2 main effects, 1 interaction). Example: Two-Factor ANOVA to evaluate the effect of Video Game Violence and Grade on Aggression Factors1. Factor A: Video Game Violence level (3 levels: low, moderate, high) 2. Factor B: Grade level (4 levels: 1st grade, 2nd grade, 3rd grade, 4th grade) 3. Dependent Variable: Aggression Hypothesis Tests1. Video Game Violence level affects Aggression2. Grade level affects Aggression 3. Interaction between Video Game Violence level and Grade level: video game violence level will affect aggression but only for 3rd and 4th graders but not for 1st and 2nd graders.
