 Q1: Daffodil bulbs are sold in boxes of 200. It is known that 2% of daffodil bulbs fail to grow. X is the random variable for the number of failed bulbs. What type ofprobability distribution best describes this situation? A. Binomial B. Poisson C. Normal D. Rectangular Answer 1: A                    B                    C                    D Q2: Could the Poisson distribution be used as a suitable approximation for X? A. Yes B. No Answer 2: A                    B                    C                    D Q3: In question 1, if the Poisson approximation was used, what would be the mean of the Poisson approximation? A. √ 2 B. 4 C. 16 D. 2 Answer 3: A                    B                    C                    D Q4: In question 1, if the Poisson distribution was used, what would be the probability that NO bulbs failed to grow. A. 0.02 B. 0.0733 C. 0.0183 D. 0.1353 Answer 4: A                    B                    C                    D Q5: In question 1, if the Poisson distribution was used, what would be the probability that more than 3 bulbs would fail to grow?
