... If the results are statistically significant at the .05 level it means the following: (1) we will reject the null hypothesis 100% of the time; (2) 95% of the time we will have made the correct decision because the null hypothesis will be false 95% of the time; (3) 5% of the time we will have committ ...

+ Conditional Probability and Independence
... If A and B are independent events, then the probability that A and B both occur is P(A ∩ B) = P(A) • P(B) Example: Following the Space Shuttle Challenger disaster, it was determined that the failure of O-ring joints in the shuttle’s booster rockets was to blame. Under cold conditions, it was estimat ...
