5 Step Hypothesis Testing Example. Since the z test statistic z -25 is less than -196 there is sufficient evidence against H 0. Test statistic replace t with z and replace s with σ below TI 83. Hypothesis Testing Step 3. Hypothesis Testing Step 4.
P neq 050 The words is different from tell you this is a two-tailed test. Given a real life example this posting asks us to perform the 5 step hypothesis testing to see if there is any significant differences in waiting times at a supermarket. Step 2 Find the critical values from the appropriate table. We have a sample. This is the same procedure that we used to conduct a hypothesis test for a single mean single proportion difference in two means and difference in two proportions. Step 3 Determine cutoff sample score on comparison distribution at which the null hypothesis should be rejected.
Random sample σ2 known population is normally distributed or n 30.
Random sample σ2 known population is normally distributed or n 30. Step 5 Summarize the results. Step 1 Restate the question as a research hypothesis and a null hy- pothesis about the populations. Step 2 Determine the characteristics of the comparison distribu- tion. We have a sample. Given a real life example this posting asks us to perform the 5 step hypothesis testing to see if there is any significant differences in waiting times at a supermarket.
