R. lfa-03, and ?-.40, 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) 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) The statistical decision is to fail to reject the null, and Ho is really false (ie a Type II error) 017: A researc her wants to determine whether high school students who attend an SAT aration course score significantly different on the SAT than students who do not attend the prep course. For those who do not attend the course, the population mean is 1050 (H 1050). The 16 students who attend the preparation course average 1150 on the SAT, with a sample standard deviation of t00. On the basis of these data, can the researcher conclude that the rse has a significant difference on SAT scores? Set alpha equal to 01 preparation co Q18: The appropriate statistical procedure for this example would be a A. t-test B. z-test Q19: Is this a one-tailed or a two-tailed test? A. one-tailed B. two-tailed Q20: The most appropriate null hypothesis (in words) would be A. There is no statistical difference in SAT scores when comparing students who took the SAT prep course with the general population of students who did not take the SAT prep course B. There is a statistical difference in SAT scores when comparing students who C. The students who took the SAT prep course did not score significantly higher D. The students who took the SAT prep course did score significantly higher on took the SAT prep course with the general population of students who did not take the SAT prep course on the SAT when compared to the general population of students who did not take the SAT prep course the SAT when compared to the general population of students who did not take the SAT prep course Q21: The most appropriate null hypothesis (in symbols) would be A. SATprep 1050 B. psAT repi, 1150 C. ?ATprep 1050 D. SATprep 1050 Set up the criteria for making a decision. That is, find the critical value using an alpha-01. (Make sure you are sign specific: +-, or ± ) (Use your tables) 022: Summarize the data into the appropriate test statistic 023: What is the numeric value of your standard error?Explanation / Answer
14. Probability of the statistical decision to reject the null hypothesis and the null hypothesis is really true is the level of significance that is given 0.3.
15. Probability of the statistical decision to fail to reject the null hypothesis and the null hypothesis is really true is =1-0.3=0.7.
16. Probability of the statistical decision to reject the null hypothesis and the null hypothesis is really
False is =0.4 which is power of a test which is given.
17. Probability of the statistical decision is to fail to reject the null hypothesis and the null hypothesis is really false=1-power =1-0.4=0.6 =that is probability of type 2 error.
