Each day he flips a coin to determine which way to go, driving each route 20 days. He finds that Route A takes an average of 40 minutes, with a ...

... • Argue that to sample from fa, one can do a two stage sampling. Stage 1, determine the state, f or δa by sampling uniformly from [0, 1]. If the sample is in [0, 1 − ] then the state is f , otherwise it is δa . Next, sample from the appropriate distribution. • Write a computer program to sample fr ...

cross-tabulation
... While conducting cross-tabulation analysis in practice, it is useful to proceed along the following steps: * Test the null hypothesis that there is no association between the variables using the chi-square statistic. If you fail to reject the null hypothesis, then there is no relationship. * If H0 i ...
