se the following scenario in your answering of questions 9 and 10. (Use the same answer choices for each question.) From a sampling frame of 1000 individuals (500 men and 500 women), a sample of 100 is to be selected, with the desired sample consisting of 40 men and 60 women. 9. Which of the following methods describes probability sampling? 10. Which of the following methods describes stratified sampling? A. Each person is assigned a three digit number (from 000 to 999). On a Random Digit Table, numbers are read, three at a time. The first hundred three-digit numbers read will represent the people in the sample. B. To make the sampling frame a more manageable size, only people with birthdays from June 1 to December 31 will be considered. From that reduced sampling frame, the method described in Answer Choice A will be used. C. Every man in the sampling frame will be assigned 8 sequential 4-digit numbers (from 0000 to 3999; example: 0000, 0001, 0002, 0003, 0004, 0005, 0006, 0007), and every woman in the sampling frame will be assigned 12 sequential 4-digit numbers (from 4000 to 9999; example: 4000, 4001, 4002, 4003, 4004, 4005, 4006, 4007, 4008, 4009, 4010, 4011). From a Random Digit Table, groupings of 4 numbers will be read and the first 100 subjects with their number read will be in the sample (duplicate selections will be ignored). D. From an alphabetized list of people in the sampling frame, the first hundred are selected. E. Each man in the sampling frame is assigned two sequential three-digit numbers (from 000 to 999; example: 000, 001). From a Random Digit Table, groupings of three numbers at a time are read. The first 40 three-digit numbers will represent the men selected (duplicate selections will be ignored). Then, each woman in the sampling frame will be assigned two sequential three-digit numbers (from 000 to 999; example: 000, 001). From a Random Digit Table, groupings of three numbers at a time are read. The first 60 three-digit numbers will represent the women selected (duplicate selections are ignored). These 40 men and 60 women will together form the sample of 100 people.
