Question 1 Practice similar questions Prev Score: 0 of 5 points Match the key terms with each context listed below. A company wants to estimate the mean time it will take workers to complete a certain task. They record the times to complete the task for a random sample of 30 workers. a. individual b. population c. sample d. statistic e. parameter f. variable \( \square \) a worker from this company \( \square \) time to complete a certain task \( \square \) 30 workers from this company \( \square \) all workers from this company \( \square \) mean time to complete a certain task for all workers from this company

Sure, let's match each context with the appropriate key term: 1. **A worker from this company** - **a. individual** - **Explanation:** An individual refers to a single member of the population. 2. **Time to complete a certain task** - **f. variable** - **Explanation:** A variable is a measurable characteristic that can take on different values. 3. **30 workers from this company** - **c. sample** - **Explanation:** A sample is a subset of the population used to estimate characteristics of the whole. 4. **All workers from this company** - **b. population** - **Explanation:** The population includes all members of the group being studied. 5. **Mean time to complete a certain task for all workers from this company** - **e. parameter** - **Explanation:** A parameter is a numerical characteristic of the entire population. **Summary of Matches:** - **a worker from this company** → **a. individual** - **Time to complete a certain task** → **f. variable** - **30 workers from this company** → **c. sample** - **All workers from this company** → **b. population** - **Mean time to complete a certain task for all workers from this company** → **e. parameter**
