Ans. #3

D

Ans. #4

Risk is simply the probability of occurrence of an undesirable outcome.
Risk analysis is an approach for developing a comprehensive understanding and awareness of the risk associated with a particular variable of interest.

Ans. #5

H0 : 1 = 2 = 3 = 4
H1 : i  j for at least one pair (i, j)
Since p-value = 0.0067, H0 is rejected at  = 0.05. We conclude that the population mean ratings for at least two of the four dormitories are not the same.
