between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. The F-value is high enough at the 5% level of significance to suggest a significant difference between the control and treatment groups. The p-value 0.005 < 0.05 hence this suggests a rejection of the null hypothesis‚ meaning that the control and treatment groups are found to be different.

Without valid results from a test the test should not be used in during the selection process of new employees. It is very important that the design of a selection process is handled carefully and accurately to ensure that the company is

probability value (often called the p value). The p-value is the probability of obtaining the test value as large as the observed value‚ when the null hypothesis was really true. Thus it can be interpreted as the probability of wrongly rejecting the null hypothesis. This is to be calculated by using the sampling distribution of the test statistic. Step5. The p value computed in Step 4 is compared with the significance level chosen in Step 2. If the p value is less than or equal to the significance

Practice with p-values Work through these problems with your computer partner and/or instructor. Answers follow the problem set. 1. Suppose we’ve done the computation of the Z test statistic. For each of the following situations determine the p-value that goes along with Z. a. Z = 2.12‚ two-sided test b. Z = 4.55‚ two-sided test c. Z = -1.40‚ lower-tail test 2. Suppose Z = 1.92.Which has a smaller p-value‚ the upper-tail test or the two-sided test? From this‚ is it more likely to have a

the p-value for the two-tailed test was determined to be 0.55‚ because this is greater than our level of significance‚ we cannot reject our null hypothesis and can conclude with 95% level of confidence that the two methods do not differ in completion times. To test the population variances we also conducted a hypothesis test about the equality of the two variances.
