Question
Observations on burst strength (lb/in^2) were obtained both for test nozzle closure welds and for production canister nozzle welds. Test 7200 6100 7300 7300 8000 7400 7300 7300 8000 6700 8300 Canister 5250 5625 5900 5900 5700 6050 5800 6000 5875 6100 5850 6600 A comparative is given below. Comment on interesting features (the cited article did not include such a picture, but the authors commented that they had looked at one). (Select all that apply.) The production canister welds have consistently lower burst strengths than the test nozzle welds. The test nozzle welds data contain 2 outliers. The production canister welds have much more variable burst strengths. The production canister welds data contain 2 outliers. The production canister welds have much higher burst strengths. The test nozzle welds have much more variable burst strengths.Explanation / Answer
the production canister welds have consistently lower burst strengths than the test nozzle welds. There is only one exception which is the outlier in canister.
The production canister welds data contain 2 outlier. These outliers are located each side of the box plot.
As we see test nozzle welds are spread from burst strenght of 6000 to 8400. This means the test nozzle welds have much more variable burst strengths.
