b.
Answer to Problem 9CRE
The probabilities are 0.28, 0.32, 0.20, 0.14 respectively.
Explanation of Solution
Calculation:
The probability that randomly chosen seedling has been damaged given each cover can be calculated as:
The required probabilities are 0.28, 0.32, 0.20, 0.14 respectively.
c.
To find: Whether the known amount of cover is changing the probability of deer damage
c.
Answer to Problem 9CRE
Yes, it is changing the probabilities.
Explanation of Solution
From part (a) and (b), it is known that
The probabilities are not same. Thus, the
