LEM. 65'ig ma 5102 56.31 I'll": SPC 1. is this new yellow fuzz different from your previous product? Prove by testing the H": p=5?.oo. HI: :1\": 5?.oo]{ hypothesis .'. for o = 0.05. Use the T-test statistic. {10] 2. Double check your answer by finding the confidence bounds on the mean bounce height. Do your results agree? Corn ments?|[10] 3. Assuming that this was a screening experiment, what do you do next andfor what do you tell your boss about both your existing data and your ideas for the future? :5] 'Iul'ermont invests about $4.5 millionfyear in anti-smoking efforts. But of 100.000 'III'T high school students 1?.600 smoke. In New Hampshire no money is spent on antismoking campaigns and 20.300 out of 100.000 HS students smoke. Using the Poisson distribution. can 1lI'ermont argue that their program has some positive effect? [15} An election poll concluded that two candidates were tied at 50% of polled voters each. The number of people polled was 500 . I|l'll'hat is the statistical error at a 95% confidence level? Comment on the results. Hint: Use the continuous approximation to the binomial disb'ibution . This type of result will be similar to when polls are reported on the news and the newscaster will sayI that the error is plus and minus 391;. 15} A. Discuss the differences between special cause and common cause failures or variation. giving at least one example of each. How might you see the difference in your measurements? [5] B. Discussion the difference between attribute and variables data. HOW do they work togetherin an effective SPC Program? (5} C. I|l'Il'hat is a Pareto Chart? How is it used in a continuous improvement program? [5] The USGA announced that they are going to be very "tough" in enforcing the rule that the maximum coefficient of restitution {[200] for golf club drivers be 0.03. [some drivers were measured by them as 0.85. this COR gives a drive 5 yards or so advantage over one thatis"in spec." Assume that the lower spec limit is 0.?0II The USGA will allow the upper spec limit on any manufacturer's driver to be 0.33 as long as the Cpk is at least 2.0 . Ping has developed a very repeatable process for making the driver heads that they believe can achieve a Cpl: of 2 with the average COR being 0.823. if this is true what must 0 be? {5]
