Problem 3 current technology uses lasers for the inspection of solder-joint defects on printed circuit boards (pcbs). a particular manufacturer of laser-based inspection equipment claims that its product can inspect on average at least 10 solder joints per second when the joints are spaced 0.1 inch apart. the equipment was tested by a potential buyer on 30 different pcbs. in each case, the equipment was operated for exactly one second. the number of solder joints inspected on each run is found in the homework 2.xlsx file. the potential buyer wants to know whether the sample data refute the manufacturer’s claim. formulate appropriate hypotheses and answer with 95% confidence
