Explanation / Answer

Hints: Label: If we use random number table to make these assignments 1) Each entry in the table is equally likely to be any of the 10digits 0 through 9. 2) The entries are independent of each other. That is, knowledgeof one part of the table gives no information about any otherpart. We must label the patients as 00001,00002,......, 19185. Random Table: To choose an SRS, read from Table successivegroups of digits of the length you used as labels. Your samplecontains the individuls whose labels you find in the table.
