Question
E. Drawing Conclusion About Population Proportion Based on Test Statistic Value and Rejection Region Directions: Compute the test statistic. Fill in the blank with the word REJECT if the decision is to reject the null hypothesis. Otherwise, write FAIL TO REJECT. Then, draw your own conclusions by completing the statement. A research states that 28% of college degrees are from engineering courses. A researcher doesn't believe that this is correct. A sample of 1,000 graduates was used and it was found out that 295 have finished engineering courses. Test the claim if it has increased at a = 0.10 level. What is the correct null hypothesis? a. Ho p = 0.28 Ha : p > 0.28 b. Level of Significance: a = 0.10 c. Computed Test Statistic: zcom = d. Critical Value: 1.282 does not fall e. DECISION: Since the computed test statistic zcom = in the rejection region, the null hypothesis (Ho). CONCLUSION: Therefore, we conclude that at 0.10 level of significance, that evidence to conclude
