Question

1. mr. jennings put student names in a hat and selected four names without looking. what type of sample did he form? a. biased sample b. convenience sample c. simple random sample d. systematic random sample

Explanation:

A simple random sample is one where every member of the population has an equal chance of being selected. Mr. Jennings putting names in a hat and selecting without looking gives each student an equal probability of being chosen. It's not a biased sample as there's no pre - determined favoritism, not a convenience sample which is based on ease of access, and not a systematic random sample which follows a pattern (like every 5th person).

Answer:

C. simple random sample
