- The state would like to evaluate the usefulness of a program to randomly test high school athletes for steroid use. Initially, a state agency will test athletes in all 20 schools in Fort Worth, randomly selecting 3 athletes from each school. What type of sampling is being employed in this example? convenience sampling cluster sampling simple random sampling stratified samplingRace organizers want to survey the participating runners on the quality of the running course. Which of the following uses systematic random sampling? Select the first 15 finishers and the last 15 finishers to take the survey. Randomly select 15% of the male participants and 15% of the female participants. Select the 5th finisher (with the number 5 being randomly chosen) to survey, then survey every 15th finisher after that. Sort all of the runners' names alphabetically, then randomly choose 2 letters and survey all participants whose last name begins with one of those letters.A coach is interested in how many slam dunks the average college freshman at his university can do.

- QuickVote. TalkBack Live, a production of CNN, conducted on-line surveys on various issues. One survey, called a QuickVote, of 680 people asked “Would you vote for a third-party candidate?” Of the 680 people surveyed, 608 (89.4%) responded “yes” and 72 (10.6%) responded “no.” Beneath the vote tally, the following statement regarding the sampling procedure was found: This QuickVote is not scientific and reflects the opinions of only those Internet users who have chosen to participate. The results cannot be assumed to represent the opinions of Internet users in general, nor the public as a whole. The QuickVote sponsor is not responsible for content, functionality or the opinions expressed therein. Discuss the preceding statement in light of what you have learned4Suppose you recruit the next 100 people who visit the DCC cafeteria to participate in a survey. One of the questions you ask is whether the student eats on campus (i.e., in the cafeteria) regularly, and you want to use the sample proportion to estimate the value of the (population) proportion of all DCC students who eat on campus regularly. Do you think this sampling method is likely to be biased? If so, in which direction? This sampling method is not likely to be biased and will produce a representative sample of DCC students. This sampling method is biased and is likely to yield an overestimate for the population proportion. This sampling method is biased and is likely to yield an underestimate for the population proportion.
- A market research company is conducting research on the preferences of college students. Due to the K-12 transition, there is 50% more freshmen and sophomores than juniors and seniors. The research team targets to get 75 freshmen, 75 sophomores, 50 juniors and 50 seniors. What sampling method do you think the research team is using? Group of answer choices: Convenience Sampling Stratified Random Sampling Quota Sampling Snowball SamplingWhat is the sampling method described? The population is divided into groups where similar cases are grouped together. Then second sampling method is employed to sample the cases within each group. a. A simple random sampling b. Stratified sampling c. Cluster sampling d. Multi-stage samplingA marketing expert for a particular chain of restaurants is planning a survey in which 510 people will be randomly selected from each age group: 10-19, 20-29, and so on. What type of sampling is used? Convenience sampling Simple random sampling Systematic sampling Stratified sampling Cluster sampling Is the procedure likely to yield a representative sample or a biased sample? Explain why. A. The procedure is likely to yield a representative sample because it covers every age group. B. The procedure is likely to be biased because people from those age groups are not evenly distributed throughout the population. C. The procedure is likely to yield a biased sample because younger people don't know what they want and should be studied separately. D. The procedure is likely to be representative because 510 people from each age group form a large sample size.
