PQ Systems through it’s Quality eline newsletter brings us another quality quiz by Professor Leary.
For this month’s quiz, and a chance to win a copy of the newly-released collection of Quality Quiz Classics. Submit your response by June 28 to be entered in the drawing.
Here’s the quiz:
Quinn Quip, our hero of sample size, decided that all that thinking last month merited a short vacation, where he continued to ponder the implications of sample sizes that produce sample proportions that fall within 2 percent of the proportional mean. Reviewing formulas, textbooks, and video training, he remembered that the sample size of 2400 would mean that he could be 95 percent confident that the sample proportion would be within 2 percent of the true proportion. (Remember that = 5 was used as a conservative estimate for sample size.)
Winners of last month’s quiz and a copy of the Quality Quiz Classics DVD:
Benjamin Ayers (Bridgestone)
Dr. Sofica Bistriceanu (EGPRN, NAPCRG)
Diane Dixon (Future Electronics)
Andrew McDonald (Davey Water Products)
Debbie Meeks (Sentara Healthcare)
