Fishing Q&A
Statictis Question: manufacture of Trilene?
The manufacturer of Trilene braided fishing line claims that the average number of gamesfish that can be landed before the line needs to be replaced on the reels is 5,000. the statandard deviation of the number of fish land is 600. Denny sampled 60 of his big game rods on his fleet of sport fishing boats and determined that the average number of fish landed before the line had to be replaced was 4800. Does Danny have a product liability complaint at the 0.10 significance level? Was Danny's experiences in performance different from that clamined by Trilene?

- Null: Mean = 5000 Alternative: Mean < 5000 alpha = .10 critical z = -1.645 reject null is test z < -1.645 standard error = 600/(sq rt 60) = 77.46 test z = (4800 - 5000)/77.46 = -2.58 reject null - which implies average is below 5000. There may be reason for a liability complaint. Danny received a performance below the manufacturer's claim.
