Transcribed Image Text:Title: Understanding Sampling Distributions and Population Medians
---
**Overview:**
In this exercise, we are examining the sampling distribution of medians from a small population consisting of the number of people in households: 1, 2, and 12. We are assuming that samples of size \( n = 2 \) are randomly selected with replacement from this population. Here are the different samples:
1,1 ; 1,2 ; 1,12 ; 2,1 ; 2,2 ; 2,12 ; 12,1 ; 12,2 ; 12,12.
**Objective:**
The goal is to analyze the medians of these samples and understand the relationship between sample medians and the population median.
---
**Part (a): Sampling Distribution of Sample Medians**
Find the median of each of the nine samples, then summarize them into a probability distribution table of distinct median values.
**Table:**
- Sample Median: List of medians to be calculated.
- Probability: Corresponding probability for each sample median.
**Instructions:**
- Insert integers or fractions.
- Use ascending order of sample medians.
---
**Part (b): Comparison of Population Median and Sample Median Mean**
Analyze the relationship between the population median and the mean of the sample medians. Select the correct statement:
- **A.** The population median is equal to the mean of the sample medians.
- **B.** The population median is equal to double the mean of the sample medians.
- **C.** The population median is not equal to the mean of the sample medians (nor half or double).
- **D.** The population median is equal to half of the mean of the sample medians.
---
**Part (c): Evaluation of Sample Medians as Estimators**
Examine if sample medians accurately estimate the population median, and evaluate their effectiveness as estimators.
- **A.** Sample medians target the population median, making them good estimators.
- **B.** Sample medians do not target the population median, yet are good estimators.
- **C.** Sample medians do not target the population median, making them poor estimators.
- **D.** Sample medians target the population median but are poor estimators.

By understanding the sampling distribution of medians, students will gain insights into how sample statistics relate to population parameters, particularly in the context
