A researcher wants to estimate the average weekly overtime hours for an employee in 80 government departments. He decided to use a random cluster sampling of two stages if he knew that the number of employees in these departments is M=50. It was found that MSB=15.5, estimate the size of the sample required for the study (find m, n respectively) , if Select one: a. m = 16 , n = 2 b. m = 3, n = 17 c. n = 3 , m =17 d. n= 16, m = 2

A particular part that is used as an injection device is sold in lots of 10. The producer deems a lot acceptable if no more than one defective is in the lot. A sampling plan involves random sampling and testing 3 of the parts out of 10. If none of the 3 is defective, the lot is accepted. Comment on the utility of this plan. Determine the correct parameter.

Q1. Highlight the target population, identify the sampling technique used, and calculate the sample size for the cases listed below. Students may use Krejcie and Morgan (1979) table where required. John worked in a FMCG with 2000 employees. He calculated a sampling fraction of 1/5. Using the employee list available with HR department, he assigned each employee a unique number. John selected first employee at random from the early 5 in that list and continued to select every fifth employee onwards. Talha needed to ensure that the total of 900 staff from all the three departments of a university was represented correctly in his research. His sampling frame…
