Question
>>Determine the appropriate nonparametric test. Weight of a Vehicle and Chest Injuries. Does the weight of a car affect chest injuries in a crash? To answer this question, data were obtained from car crash experiments conducted by the National Transportation Safety Administration. New cars were purchased and crashed into a fixed barrier at 35mph and the chest deceleration data are given below. Which test could be used to find out if heavier vehicles are safer in a crash?
a)Single Sample Signed Test
b)Wilcoxon Rank Sum Test
c)Wilcoxon Signed-Rank or Paired Sample Signed Test
d)Kruskal Wallis Test
e)Spearman Rank Correlation Coefficient Test

Question 24:
Here we have more than two groups to test and we want to use non parametric test so d)Kruskal Wallis Test will be used.
Question 25:
Here we have two independent groups "One is funding and second is enrollment" to compare so b)Wilcoxon Rank Sum Test will be used.
