The editor hires a polling firm to conduct a survey and requests that a sample of 500 residents be selected using a stratified sampling design based on voting districts within the city. Which of the following methods will achieve the desired sampling design?

• Send a survey to all city residents and use the first 500 returned surveys for the sample.

• Select a random sample from each voting district based on the proportion of city residents in the district so that a total of 500 is obtained.

• Select one voting district at random, and then select a random sample of 500 from the selected voting district.

• Alphabetize a list of all city residents, and then select the first 500 residents on the list, classifying those selected by voting district.

• Select the first 500 city residents who attend the next high school football game.

The buyer for an electronics store wants to estimate the proportion of defective wireless game controllers in a shipment of 5,000 controllers from the store's primary supplier. The shipment consists of 200 boxes each containing 25 controllers. The buyer numbers the boxes from 1 to 200 and randomly selects six numbers in that range. She then opens the six boxes with the corresponding numbers, examines all 25 controllers in each of these boxes, and determines the proportion of the 150 controllers that are defective. What type of sample is this?

• Convenience Sample

• Simple Random Sample

• Systematic Sample

• Stratified random sample

• Cluster random sample

• Yes, because the sample size is large.

• Yes, because only people entering the mall were given the survey.

• Yes, because the sample was representative.

• No, because a random sample from all customers of the shopping mall was not selected.

• No, because not all customers were selected.

A professor at a large university plans to conduct a study to compare the effect of online texts versus regular printed texts on student learning. If the findings are to be generalized to all students at the university, which of the following must be part of the design?

• The students in the study should have experience using online and regular texts.

• The students in the study should be a random sample from the population of students at the university.

• The students should be allowed to choose which type of text they would like to use so that different learning styles are taken into consideration.

• The professor should collect data from all students in the population before generalizing results.

• Only volunteer students should be used in the study because they are more likely to be active participants.
