Find the Sample Size of the following Population: 1. 5.235 4. 50.000 2. 2.000 5. 15.752 Slavin's formula: N 1+ Nel N - Population Ster a . Sample Sire 3. 8.700 - Margin of Error (use the standard)10. A systematic sampling is a sampling technique in which a list of elements of the population is used as a sampling frame and the elements to be included in the desired sample are selected by skipping through the list at regular intervals. 2 of 2 Identify the sampling technique to be used and determine the samples in each problem. 1. A researcher wishes to select a sample of n - 35 students from a population of 2, 500. Use the Table of Random Numbers to identify the students to be included in the sample. 2. There are 120 teachers. Select a sample of 40 teachers by using the systematic sampling technique. 3. Marcela, a Statistics student, wants to determine who care more about their physical appearances, the male or the female students. She wants to limit her study to the Grade 10 students. There are unequal numbers of Grade 10 students: 340 are male and 500 are female. She wants her sample to consist of 50 students. What is the appropriate sampling technique to be used in the problem? 4. A population contains 10, 000 employees. Use the Table of Random Numbers to identify the employees to be included in the sample of n= 40. 5. A researcher wants to select 35 people from a population of 150. How is she going to do it by the systematic sampling technique? 6. A researcher wants to determine who among the following ages are spending the most of their time in social media. The distributions of the population according of ages are as follows: 12-20= 300, 21-35 - 700, 35-50 = 600, 50-80 = 450. If the sample is n-260. identify the number of samples per strata. Solve for the following problem. 7.
