Answer

# Brief Explanations: For Sampling Task Card 4: Mrs. Jones selects names from a hat without looking. This gives each student an equal chance of being selected, which is the characteristic of random sampling. For Sampling Task Card 5: Lee calls every tenth name in the directory. This is a form of systematic sampling which is a type of random sampling as long as the starting - point is randomly chosen. Here we assume a random start and it is a form of random sampling. For Sampling Task Card 6: Mr. Dawson surveys people standing in line at a movie theater. This is convenient for him to conduct the survey, so it is convenience sampling. # Answer: Sampling Task Card 4: C. random sampling Sampling Task Card 5: C. random sampling Sampling Task Card 6: B. convenience sampling
