question 144

Short Answer

SCENARIO 3-14-B
You are the quality control manager of a water bottles company. One of the biggest complaints in the
past years has been the breakage and, hence, the concern on the durability of the connector between
the lid and the bottle which many users use as a handle for the bottles. To collect evidence before
implementing any modification to the production process, your department has subjected 100 water
bottles to a durability test and the following data on the number of times the handles have been used
to lift the bottles before they break are contained in the file Scenario3-14-DataB.XLSX. $$\begin{array} { l l l l l l l l l l } 493 & 506 & 515 & 491 & 500 & 505 & 517 & 510 & 506 & 503 \\503 & 491 & 495 & 496 & 496 & 505 & 493 & 486 & 504 & 483 \\514 & 494 & 497 & 501 & 493 & 490 & 510 & 494 & 494 & 495 \\494 & 486 & 495 & 506 & 506 & 507 & 502 & 498 & 510 & 501 \\500 & 505 & 492 & 486 & 501 & 496 & 501 & 521 & 510 & 498\end{array}$$
