Under the normal curve, the critical values separate the rejection region from the rest. D. When confidence level is 95%, alpha level is 0.05 2. What does it imply if the NULL hypothesis is being accepted? A. The alternative hypothesis also accepted B. There exists a significant difference between parameters C. The computed test statistic is greater than critical value D. The two parameters don't have a significant difference 3. What do you call processes involved in making conclusions about population values? A. Estimating parameters C. Hypothesis Testing B. Inferential Statistics D. Descriptive Statistics 4. What do you call to the probability that a parameter is contained in a range of values? A. Confidence Level C. Confidence Interval B. Confidence Coefficient D. Confidence Limit 5. Which of the following are the 95% confidence coefficients? A. -/+1.645 C. -/+2.33 B. -/+1.96 D. -/+1.6452.58 For numbers 6 -10 refer to the situation below An experimental study was conducted by a researcher to determine if a new time slot has an effect on the performance of Grade 11 students in Statistics and Probability. 25 randomly selected learners participated in the study. Toward the end of the investigation, a standardized assessment was conducted. The sample mean was 83 and the standard deviation is 2.75, In the standardization of test the mean was 80 and standard deviation is 1.2, use alpha level 0.05 to test the if the new time slot is effective. 6. What could be the possible Null hypothesis? A. The new time slot has an effect on the performance of Grade 11 students B. The new time slot is effective C. There is a significant difference between the mean D. There is no sufficient evidence that new time slot is effective 7. What is the confidence level of the situation above? A. 99% B. 90% C. 95% D. 85% 8. What is the critical region? A. 1.96 B. 1.645 C. 2.33 D. 2.58 9. What is the computed test statistic? A. 10.56 B. 12.5 C. 8.00 D. 5.45 10. What is your decision? A. Accept the Null Hypothesis B. Reject the Null Hypothesis C. Do not Reject the Alternative Hypothesis D. Reject the Alternative Hypothesis
