Who is Net ?
400

400
The condition that causes P(A|B) = P(A)
What is A and B are INDEPENDENT ?
400
The difference between an observed value of the response variable and the value predicted by the regression line.

10% of adults belong to health clubs. and 40% of these health club members go to the club at least twice a week. What percent of all adults go to a health club at least twice a week?
let H = adult belongs to health club and G = adult goes to club at least twice a week.
P(G and H) = P(H) X P(G|H) = 0.1 x 0.4 = .04

1. two outcomes (success and failure)
2. independent trials
3. fixed number of trials
4. probability of success does not change
What are the CONDITIONS or the SETTING of a BINOMIAL probability problem?
500
A point on a scatterplot that if it were removed would have a significant impact on the slope of the LSRL.
What is an influential point or an outlier ?
500
If this condition is met, we can use the Normal curve to approximate the distributiion because the results "with replacement" vs "without replacement" will be statistically insignificant.
Why do we use Rule of Thumb #1 : the population must be at least 10 times the size of the population.
