Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain. After a tsunami, a disaster area is divided into 250 equal grids. Thirty of the grids are selected, and every occupied household in the grid is interviewed to help focus relief efforts on what residents require the most. What type of sampling is used? A. Stratified sampling is used, since the disaster area is divded into grids, and a random sample is taken from each grid. B. Cluster sampling is used, since the disaster area is divded into grids, and a random sample is taken from each grid. C. Stratified sampling is used, since the disaster area is divided into grids, and some of those grids are selected and everyone in those grids is interviewed. D. Cluster sampling is used, since the disaster area is divided into grids, and some of those grids are selected and everyone in those grids is interviewed. What potential sources of bias are present, if any? Select all that apply. A. Certain grids…
Chemistry grades 2A are Brown 70, John 85, Christ 99, Ryan 56, Dovy 87, Megan 48, Zory 77, Vroy 65, Hyu 88, and Sue 86. If 6 samples are taken, what is the sampling error? is error in sampling still tolerable?
You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 90% confident that the sample percentage is within 5.5 percentage points of the true population percentage. Complete parts (a) and (b) below. a. Assume that nothing is known about the percentage of passengers who prefer aisle seats. (Round up to the nearest integer.) b. Assume that a prior survey suggests that about 38% of air passengers prefer an aisle seat. (Round up to the nearest integer.)

Identify the sampling method (simple random sampling, systematic sampling, convenience sampling, or stratified sampling) in the following studies a. You split the population into faculty and students and then choose a random sample from each. b. You assign each member of the population a number and choose the sample using a computer program that randomly picks numbers. c. You ask every 3rd person who walks into the store to complete a survey.
