... computing a p-value, the probability of a more extreme test statistic than the one observed if the null is true. • A small p-value indicates we should reject the null hypothesis. • A large p-value means there is not strong evidence against the null. • At the end of the test, we either reject or fail ...

... 13. Why do we assume that the variation of Y for fixed values of the independent variables is the same regardless of the values of the independent variables? a. needed for normality b. so that the model stays linear c. only if the sample is random and independent d. simplicity 14. You decide to use ...

... One way to determine the confidence interval is to repeatedly draw samples. The sample estimate of a parameter is computed for each sample. An examination of the variations of the estimates across all samples will give us an idea of how different the estimates are. For example, if we want to estimat ...

... To avoid bias we must randomly select subjects or experimental units from the population being studied. There are 4 basic systems of random selection we have studied. simple random samples – the best method overall – number ALL possible subjects in the population. Then use a random number generator ...
