Chapter 10 Tan Boxes Flashcards
Finding shape for sampling distribution p1-p2
fulfilling all of the normality equations for each sample
Finding center for sampling distribution p1-p2
p1-p2
Finding spread for the sampling distribution p1-p2
one square root sign is used
Finding independence for p1-p2
the 10% condition must be met in both samples
When the probability falls on the right end of the Gaussian curve
Ha: p1-p2 > 0
When the probability falls on the left side of the Gaussian curve
Ha: p1-p2 < 0
When the probability falls on both ends of the Gaussian curves
Ha: p1-p2 does not equal zero
Finding normality for the sampling distribution X1-X2
When both the samples have populations over 30,
Find independence for sampling distribution X1-X2
Both samples must follow the 10% condition
Can a sample with size 15 or less be normal
yes, if little skew and outliers
