Question 717083: Please help with this calculation, please show full workings. Many thanks.
The president of a company that manufactures air conditioners is considering switching his supplier of condensers. Supplier A, the current producer of condensers for the manufacturer, prices its product 5% (percent) higher than supplier B does. Because the president wants to maintain his company's reputation for quality, he wants to be sure that Supplier's B condensers last as least as long as Supplier A's condensers. After a careful analysis, the president decided to retain supplier A if there is sufficient statistical evidence that supplier A's condensers last longer, on average than Supplier B's condensers. In an expirement, 15 randomly-selected midsize cars were equipped using type-A condensers while another 15 randomly-selected midsize cars were equipped with type-B condensers. The number of kilometers (in thousands) driven by each car before the condenser broke down is displayed in the table below.
Carry out a hypothesis test, at 5% (percent) significance level, to determine whether the president should retain supplier A.
The numbers below from Supplier A and Supplier B are corresponding. I cant do them next to each other then it squashes them all together. Not sure why.
