07: What is the z-value or t-value you obtained ( istic o8: Based on your and comparing yo reject the null hypothesis B)fail to reject the null hypothesis 0: The best.conclusion for this example would be Q9: The is no statistical difference in the amount of time appendix patients spend in the hospital when comparing the new recovery program to the population of patients on the traditional recovery program. B. There is a statistical difference in the amount of time appendix patients spend C. The new appendix recovery program does not significantly reduce the number D. The new appendix recovery program does significantly reduce the number of in the hospital when comparing the new recovery program to the population of patients on the traditional recovery program of days spent in the hospital when compared to the population of patients on the traditional recovery program. days spent in the hospital when compared to the population of patients on the traditional recovery program. Q10: Based on your evaluation of the null in Q8 and your conclusion is 09, as a researcher you would be more concerned with a A. Type I statistical error B. Type II statistical error Calculate the 95% confidence interval. Steps: Q11: The mean you will use for this calculation is 5.8 6.3 Q12: What is the new critical value you will use for this calculation? Q13: As you know, two values will be required to complete the following equation: The following 4 questions (014 to 017) are based on the following situation probability of each. 014: The statistical decision is to reject the null, and Ho is really true (ie: a Type I error) Q15: The statistical decision is to fail to reject null, and Ho is really true (ie: a correct decision) 016: The statistical decision is to reject the null, and Ho is really false (ie: Power) lfa-.04, and -35, complete the following questions by inserting the appropriateExplanation / Answer
Q7 to Q13: initial questions and data is missing hence i cannot answer this.
Q14 to Q17
If alpha = .04 and beta = .35, complete the following questions by inserting the appropriate probability of each.
Q14 : The statistical decision is to reject the null, and Ho is really true (ie: a Type I error)
p=alpha=0.04
Q15 : The statistical decision is to fail to reject null, and Ho is really true (ie: correct decision)
p=1-alpha=1-0.04=0.96
Q16 : The statistical decision is to reject the null, and Ho is really false (ie: Power)
p=1-beta=1-0.35=0.65
Q17: The statistical decision is to fail to reject the null, and Ho is really false (ie: Type II error)
p=beta=0.35
Q18: we use z test when the sample size is above 30 and you should know standard deviation:
I am assuming there will be equal proprotion of students (Since number of students who did not attend prep course not given ) who did not attend prep course.
Hence z test is appropriate here
Q19: One Tailed test is the correct answer since researcher wants to check in only one direction
two-tailed test: With significance level of 0.01, this test allots half alpha to testing the statistical significance in one direction and half alpha to testing statistical significance in the other direction. i.e 0.005 is in each tail of the distribution of test statistic. irrespective of the direction of the relationship of hypothesis, this test checks the possibility of relationship in both directions.
one-tailed test: With significance level of .01, this test allots all the alpha to checking the statistical significance in the one direction of interest. i.e .01 is in one tail of the distribution of your test statistic. only the possibility of the relationship in one direction is checked and possibility of a relationship in the other direction is not considered.
