27. Most effective sampling techniques are based on random sampling, and our textdescribes several (e.g., simple, stratified, cluster). However, the author didn't describehow to actually create such samples. If you wanted to choose a simple random sampleof five students from our class, how would you do it? Explain. Hint: If you aren'tsure, google it.

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.)
