... times if the samples were truly equal. • The p-value for the second effect is 0.0039, which is also highly significant. This indicates that the effect of the second predictor varies from one sample to another. • Does not appear to be any interaction between the two predictors. The p-value, 0.8411, m ...

Hypothesis Testing
... A test statistic is a function of the sample data on which the decision – reject H0 or do not reject H0 – will be based This is the statistical value that will asses your evidence against the null hypothesis • For the random sampling of chips example, the test statistic would be the binomial ran ...

Confidence Intervals(new2).
... But why do we always see 95% CI’s? • “[Hypothesis tests] are sometimes overused and their results misinterpreted.” • “Confidence intervals are of more than philosophical interest, because their broader use would help eliminate misinterpretations of published results.” ...

... Let R be the continuous random variable giving the error in a geologist's estimate for the value of a lease. Experience allows us to assume that R is normal, with R = 0 and R = 10 million dollars. Suppose that the 15 companies form 3 bidding rings of equal sizes. Let M be the random variable givin ...
