### Hypothesis Testing Critical Values and Decision Making#### Example 1: Right-Tailed Test**Scenario:** Suppose the observed value of the test equals 2.45 and the critical value of the rejection region for a right-tailed test equals 2.281. What is the decision of the test?**Solution:** In this scenario, the observed value (2.45) is greater than the critical value (2.281). For a right-tailed test, if the observed value of the test statistic exceeds the critical value, we reject the null hypothesis.**Decision:** Reject the null hypothesis.#### Example 2: Left-Tailed Test**Scenario:** Suppose the observed value of the test equals -1.95 and the critical value of the rejection region for a left-tailed test equals -2.371. What is the decision of the test?**Solution:** In this scenario, the observed value (-1.95) is greater than the critical value (-2.371). For a left-tailed test, if the observed value of the test statistic is greater than the critical value, we fail to reject the null hypothesis.**Decision:** Fail to reject the null hypothesis.

A researcher gathered a sample of participants who volunteered for a studying of phobias. She measured anxiety level of participants as they viewed photos of spiders and again when they viewed puppies. Which statistical test is appropriate for this study and why?
We predict that children exhibit more aggressive act after watching a violent television show. The scores for ten children were recorded before they watched a violent show and then after they watched a violent show. Aggression was measured in terms of number of aggressive acts (e.g. hitting, yelling, kicking etc). Sample 1 (after TV show): 5,6,4,4,7,3,2,1,4,1 Sample 2 (before TV show): 4,6,3,2,4,1,0,0,5,2 What is the critical value?
The admisnistrators of Rowan university wants to know more about the knowledge of students regarding international events. They are concerned that their students are uninformed with regards to the news from other countries. When a standardized test is used to assess the knowledge of all students at al US universities about world events, it is reported that the national mean. A sample of 35 students from Rowan university are tested and the sample mean is 58 and the standard error is 3.2. The 99 percent confidence interval of population mean knowledge of the students at Rowan university has to be determined. 6. The 99 percent confidence interval of the population mean knowledge of the students at Rowan university based on this sample data is?
Suppose that Kim is a participant in a study that compares several coaching methods to see how they affect math Scholar Aptitude Test (SAT) scores. The grand mean of math SAT scores for all participants (My) in the study is 550. The group that Kim participated in had a mean math SAT score of 565. Kim’s individual score on the math SAT was 610. What was the estimate residual component (of Kim’s score, that is, the part of Kim’s score that was not related to the coaching method? (Both parts of this question call for specific numerical values as answers). What was that “effect” (ai) component of Kim's score? What pattern in grouped data would make SSwithin = 0? What pattern within data would make SSbetween = 0?
A political scientist claims that the president’s approval rating in Ogun State is lower than the president’s approval rating in Bayelsa State. To prove his point, he conducted surveys in the two states. Of the 874 individuals polled in Ogun state, 350 favored the president, and of the 1024 individuals polled in Bayelsa state, 438 favored the president. Test the political scientists claim at the 5% level of significance. The p-value of the test is
