In a standard 52-card deck, where each card is assigned a numeric value, the mean of the 52 cards is 7.0 with a standard deviation of 3.742. To test if a representative sample can be attained, the deck is shuffled and 13 cards are randomly drawn, one at a time. Each card is recorded and then returned randomly to the deck before the next card is drawn. This process of drawing 13 random cards is repeated a total of 20 times, and the mean and standard deviation of each round is computed. Which...

True experiments correct answers an experiment in which subjects are assigned randomly to an experimental group that receives a treatment or other manipulation of the IV and a comparison group that does not receive the treatment or receives some other manipulation; outcomes are measured in a posttest 3 major features of true experiments correct answers 1. two groups (experimental and a control group) 2. random assignment to the two (or more) comparison groups 3. variation in the IV before a...

If the chance that any one of five telephone lines is busy at any instant is 0.01, then what is the probability that all the lines are busy? A. (0.01)^4 B. (0.01)^5 C. (0.01)^6 D. (0.01)^10 - B. (0.01)^5 N = 5, p = 0.01, x = 5 Apply Standard formula for Binomial Distribution. Thus, option b is the correct answer. Who should complete the control phase after the successful completion and implementation of the first four phases of DMAIC? A. The green belt alone; the project has...
