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.)
A researcher is interested in determining the spending habits of the employees in a particularly large law firm . The researcher wants to gather information from at least 50 of the 167 employees . Assume the researcher has complete control over how to pick the residents to collect this data. In the box below, pick a sampling method: Random, Stratified, SystematicCluster, or Voluntary, and describe how to use it in this scenario to collect a sample that will represent the whole law firm Your description should show understanding of the method you chose and be in the context of this scenario - not just a definition of the type of sampling.
A researcher wants to survey 2000 Americans for an obesity study. Match the strategies to their corresponding sampling techniques. The researcher posts the survey on the Internet the survey question and waits until 2000 people have responded. The researcher picks 20 different small groups:a church group a Democrat club a student club etc. each containing 100 people. Then the researcher makes sure that everyone from each group answers the survey question. The researcher gets the complete list from the Census Bureau and surveys every 1500th person on the list. The researcher makes sure that the proportion of respondents from each state matches the proportion of each state's population to the US population. The researcher gets the complete list from the Census Bureau and uses a computer to randomly select 2000 people. Stratified Sampling Systematic Sampling Cluster Sampling Convenience Sampling Simple Random Sampling
