A die cutting process for sheet metal currently produces an average of 3% defectives. You are interested in showing that a simple adjustment on a machine will decrease p, the proportion of defectives produced in the die cutting process. Thus, the alternative hypothesis is H : p , .03 a and the null hypothesis is H : p5.03 0 If you can reject 0 H , you can conclude that the adjusted process produces fewer than 3%

defectives.
