Find the students that are included in the sample.
a.

Answer to Problem 1SR
The students that are included in the sample are PRICE, MARY LYNETTE, DETLEY, BRIAN HANS and MOLTER, KRISTI MARIE.
Explanation of Solution
From the given information, list of 46 students are given and assigned the numbers as 00 to 45. The selected random numbers are 31, 7 and 25.
The students corresponding to the selected numbers are 31-PRICE, MARY LYNETTE, 7-DETLEY, BRIAN HANS and 25-MOLTER, KRISTI MARIE.
Thus, the students that are included in the sample are PRICE, MARY LYNETTE, DETLEY, BRIAN HANS and MOLTER, KRISTI MARIE.
b.
Select the own sample of students using table of random digits, Appendix B.4.
b.

Answer to Problem 1SR
The own sample of students using table of random digits, Appendix B.4 are KABAT, JAMES DAVID, KILLION, MICHELLE A and LEHMANN, KRISTINA MARIE.
Explanation of Solution
The first column and the sixth row are randomly selected in the Appendix B.4. The number is 17147. From the given information, there are only 46 students. Select the first two digits of 17147. Thus, the first selected sample is 17. Continue the process by going in any direction until to get the sample of 3 students. Randomly go right from the number 17147. The first number that is right to the 17147 is 19 and the second number that is right to the 17147 is 22. Thus, the selected random numbers are 17, 19 and 22.
The students corresponding to the selected numbers are 17-KABAT, JAMES DAVID, 19-KILLION, MICHELLE A and 22-LEHMANN, KRISTINA MARIE.
Thus, the own sample of students using table of random digits, Appendix B.4 are KABAT, JAMES DAVID, KILLION, MICHELLE A and LEHMANN, KRISTINA MARIE.
c.
Give the explanation that can be done if the number 59 is encountered in the table of random digits.
c.

Answer to Problem 1SR
If the number 59 is encountered in the table of random digits, then the number 59 would not be considered and another random digit would be selected to select the sample.
Explanation of Solution
The number 59 does not exist in the list because there are only 46 students. In that situation, select another random digit to select the sample.
Thus, if the number 59 is encountered in the table of random digits, then the number 59 would not be considered and another random digit would be selected to select the sample.

- Please help me with this statistics questionarrow_forwardPlease help me with the following statistic questionarrow_forwardTo evaluate the success of a 1-year experimental program designed to increase the mathematical achievement of underprivileged high school seniors, a random sample of participants in the program will be selected and their mathematics scores will be compared with the previous year’s statewide average of 525 for underprivileged seniors. The researchers want to determine whether the experimental program has increased the mean achievement level over the previous year’s statewide average. If alpha=.05, what sample size is needed to have a probability of Type II error of at most .025 if the actual mean is increased to 550? From previous results, sigma=80.arrow_forward
