I need help on this question.

For the following report about a statistical study. identify {if possible] a] the population: o) the population parameter of interest; c] the sampling frame; d] the sample; e] the sampling method. including whether or not randomization was employed: f) who {if anyone) was left out of the study; and g} any potential sources of bias you can detect and any problems you see in generalizing to the population of interest A company packaging potato chips maintains quality control by randomly selecting 15 cases from each day's production and weighing the bags. Then they open four random bags from each case and inspect the contents. a) What is the population? C! A. The employees that produce potato chips at the company O B. Bags of potato chips produced by the company O O. The 60 total bags that are opened from the selected cases 0 D. Consumers who eat potato chips produced by the company O E. The population for this study is unclear. b) What is the population parameter of interest? C! A. The proportion ofbags with incorrect weight O B. The number of bags that contain more than the stated amount O O. The proportion of people who do not eat potato chips 0 D. The proportion of people who eat potato chips 0 E. The population parameter of interest is unclear. c) What is the sampling frame? O A. The 60 total bags that are opened from the selected cases O B. The bags that pass inspection O C. The bags that fail inspection O D. All bags produced by the company each day O E. The sampling frame is unclear. d) What is the sample for this study? O A. The 60 total bags that are opened from the selected cases O B. The bags that pass inspection O C. The 15 cases selected from production O D. It is unclear what the sample for this study is.e) What sampling method was used? O A. Multistage sampling was used. O B. Cluster sampling was used. O C. Convenience sampling was used. D. Systematic sampling was used. O E. Stratified sampling was used. O F. It is unclear what sampling method was used. Is randomization employed? O No O Yesf) What group (if any) was left out of this study? O A. The bags that do not pass inspection O B. The bags in each case that were not inspected O C. The cases produced each day that were not chosen O D. No group was left out of the study. O E. It is unclear if any group was left out of this study. f) What type of bias is evident in this sample? O A. Convenience sample bias is possible, since only 60 bags are examined each day. O B. Nonresponse bias is possible, since the bags not examined may dramatically change the proportion of bags that do not pass inspection. O C. Undercoverage bias is possible, since only 60 bags are examined each day. O D. There is no indication of bias
