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.

To determine

Select the own sample of students using table of random digits, Appendix B.4.

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.

To determine

Give the explanation that can be done if the number 59 is encountered in the table of random digits.

c.

Expert Solution

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.

4.96 The  breaking  strengths  for  1-foot-square  samples  of  a  particular  synthetic  fabric  are  approximately  normally  distributed  with  a  mean  of  2,250  pounds  per  square  inch  (psi)  and  a  standard deviation of 10.2 psi. Find the probability of selecting a  1-foot-square sample of material at random that on testing would have a breaking strength in excess of 2,265 psi.4.97 Refer to Exercise 4.96. Suppose that a new synthetic fabric has been developed that may have a different mean breaking strength. A random sample of 15  1-foot sections is obtained, and each section is tested for breaking strength. If we assume that the population standard deviation for the new fabric is identical to that for the old fabric, describe the sampling distribution forybased on random samples of 15  1-foot sections of new fabric
