the test statistic—a description of how far the point estimate (our sample statistic) falls from the parameter value in the null hypothesis P-value —an objective measure of the strength of evidence which the data supplies in favor of the null hypothesis: the probability of getting a result as extreme or more extreme than the one observed if ...

Now to compute the test statistic with the EXCEL calculator, do the following: Step1: make sure you are on the “Hypothesis Test” worksheet (there are 3 worksheets) Step2: Work under the heading: Hypothesis Test Proportion Step3: in the cell next to alpha enter .01 (the problem wants to test at 1%) Step4: in the cell next to Null enter .3

Using a One Proportion z-test, the students calculate a p-value = 0.27 and conclude that they do not have enough evidence to say that the proportion of all boxes is less than 0.20. Although the company may be cheating its customers, the students do not have convincing evidence that this is the case.

56. B The hypothesis was not rejected at level alpha=.05.So p value was higher than 0.05 and so higher than 0.025 as well. So the test will again fail to reject the null hypothesis at level =0.025. 57. A The hypothesis was rejected at level=0.01.So, p value was less than 0.01 and so less than 0.10 as well.

(using 2 – proportion . z. test on calculator we get . P≈0.00000000065 . which is clear evidence we should reject the null hypothesis and concluded that the proportion of young men and young women that live with their parents is different)We now want to look at the confidence interval by finding the difference in the sample proportions:

Test the hypothesis that two populations have equal means against either a one-sided or a two-sided alternative. Use the two-sample t test with conservative degrees of freedom if you do not have statistical software. Use the TI-83/84/89 or software if you have it. Recognize when the two-sample t procedures are appropriate in practice.
