The specification for the pull strength of a wire that connects an integrated circuit to its frame is 10 g or more. in a sample of 83 units made with gold wire, 70 met the specification, and in a sample of 115 units made with aluminum wire, 98 met the specification. find a 99% confidence interval for the difference in the proportions of units that meet the specification between units with gold wire and those with aluminum wire.
