Sampling Method Assume that the population consists of all students currently in your statistics class. Describe how to obtain a sample of six students so that the result is a sample of the given type. a. Simple random sample b. Systematic sample c. Stratified sample d. Cluster sample

Determine the type of sampling used in the following scenario. A student wants to know the average height of the class. The student asks 3 male classmates and 3 female classmates for their height. simple random sampling stratified sampling cluster sampling systematic sampling convenience sampling

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.)
