Test an appropriate hypothesis using an alpha = 0.05.What is the value of the proper test statistic? Record your answer to 4 places after the decimal point (e.g. X.XXXX).Enter answer here A plant superintendent has been assigned the task of improving the joint strength of a clutch assembly. Theassembly consists of two components: the clutch cup and the drive sprocket. The two components are joinedtogether by means of a brazing operation.The plant superintendent wanted to investigate whether changing the brazing material would affect average brazestrength. They decided he would braze one group with pure copper wire and braze another group with theexisting copper alloy. One of the two components, the sprocket, is manufactured from powdered metal.The superintendent had observed from past studies that there was a strong relationship between the density ofthe sprocket and the joint strength of the assembly after brazing. The greater the porosity of the powdered metalsprocket, the more absorption of the braze material takes place, resulting in a weaker bond.They decided to use the known relationship between sprocket porosity and joint strength for setting up amatched-pairs design. 100 sprockets were randomly selected from inventory and identified and measured fordensity. They were then rank ordered from lowest to highest and paired according to their density. Each pair ofsprockets was randomly assigned to one of two groups that were to receive the different brazing material.Once the random assignments were completed, the superintendent verified that there was no statisticallysignificant difference between the two groups for density in terms of central tendency and dispersion.The two groups were then run in pairs through the braze furnace. The braze strength of the assemblies wastested to failure in the laboratory on an Instron machine. The superintendent calculated the following statistics:Copper AlloyPure CopperMean1 = 3671 IbsMean2 = 4228 Ibss1 = 246 Ibss2 = 182 Ibsn1 = n2 = 50 (pairs)r12 = 0.78
