Question 3. A biologist watches fish swim up-stream for ten 7 minute intervals. The following is the data obtained: Interval 1 2 3 4 5 6 7 8 9 10 Number 6 5 W 2 2 10 W 5 of Fish Part A. How many fish swim up-stream, on average, every 7 minutes? Part B. What is the probability that exactly 5 fish swim up-stream in 7 minutes? Answer this by hand. Part C. What is the probability that at least 5 fish swim up-stream in 7 minutes? Use R for the final answer, but show your equation(s). Part D. What is the probability that at most 5 fish swim up-stream in 7 minutes? Use R for the final answer, but show your equation(s). Part E. What is the probability that 5 fish swim up-stream in 14 mintues? Answer this by hand. Part F. If 7 to 9 fish (inclusive) swim up-stream in 10 minutes it is called a "school". What is the probability that in 5 non overlapping 10 minute periods, we see exactly 3 schools? Answer this by hand
