## Hypothesis Testing for Regional Real Estate Company

[Your Name]

Hypothesis Testing for Regional Real Estate Company 1

Southern New Hampshire University

### Introduction

[Describe the purpose of this analysis. Briefly describe how you generated your random sample of 750 houses.]

### Hypothesis Test Setup

[Define your population parameter.]

[Write the null and alternative hypotheses.]

[Specify the name of the test you will use and identify whether it is a left-tailed, right-tailed, or two-tailed test.]

### Data Analysis Preparations

[Provide the descriptive statistics of the sample (sample size, mean, median, and standard deviation).]

[Provide a histogram of the sample.]

[Summarize your sample by writing a sentence describing the shape, center, and spread of your sample.]

[Check whether the assumptions to perform your identified test have been met.]

[Identify the test significance level. For example, α = .05]

### Calculations

[Calculate the sample mean and standard error.]

[Determine the appropriate test statistic, then calculate the test statistic. Note: This calculation is (mean – target)/standard error. In this case, the mean is your regional mean (Pacific), and the target is 280.]

[Calculate the
_p_ value using one of the following tests:]

| | |
| — | — |
| **Excel Function** | **Type of Test** |
| =T.DIST.RT([test statistic], [degree of freedom]) | Right-tailed |
| =T.DIST([test statistic], [degree of freedom], 1) | Left-tailed |
| =T.DIST.2T([test statistic], [degree of freedom]) | Two-tailed |

[
**Note:** The degree of freedom is calculated by subtracting 1 from your sample size.]

[Use the normal curve graph as a reference to describe where the
_p_ value and test statistic would be placed.]

### Test Decision

[Compare the relationship between the
_p_ value and significance level.]

[Decide to reject or fail to reject the null hypothesis.]

### Conclusion

[Explain in one paragraph how your test decision relates to your hypothesis and whether your conclusions are statistically significant.]

3. The number of oranges grown by a tree depends on how densely the trees are planted
at a farm. If 𝑛 trees are planted on an acre of land, then each tree produces 630 − 9𝑛

Prepare

Download the following documents from the Required Resources.

– Week 3 Excel spreadsheet
– Week 5 Excel spreadsheet
– Week 5 Lab Assignment Template

1. Begin with the 10 heights provided to you by your instructor. (Please reach out to your instructor by Monday in Week 5 if you have not received the 10 heights.)
2. To add 10 more values to your lab data, survey or measure 10 people to find their heights. Add these heights to the Week 5 Lab Template along with the 10 provided by your instructor.
3. Determine the mean and standard deviation for the 20 values (your instructor's 10 from Step 1A above plus your 10) by using the **Week 3 Excel Spreadsheet**.
4. Post a screenshot of the portion of the spreadsheet that helped you determine these values.
5. How does your height compare to the mean (average) height of the 20 values? Is your height taller, shorter, or the same as the mean of the sample?

![MATH225_W5_Lab_Example1.png](https://chamberlain.instructure.com/courses/206248/files/41930736/preview)

**Note:** The values in the picture above are **NOT** the values that you are to use in your lab.

Give some background information on the group of people you used in your study. Use the following questions to guide your answers.

1. How did you choose the participants for your study? What was the sampling method: systematic, convenience, cluster, stratified, simple random?
2. What part of the country did your study take place in?
3. What are the age ranges of your participants?
4. How many of each gender did you have in your study?
5. What are other interesting factors about your group?

Use the **Week 5 Excel Spreadsheet** for the following:

1. Use the **Empirical Rule tab** from the spreadsheet. Then, determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms of the 20 heights in your height study.
2. Post a screenshot of your work from the Week 5 Excel spreadsheet.

![MATH225_W5_Lab_Example2.png](https://chamberlain.instructure.com/courses/206248/files/41930601/preview)

1. What do these values tell you?
2. Post another screenshot of your work from the **Normal Probability tab** from the Week 5 Excel spreadsheet.
3. Based on your study results, what percent of the study participants are shorter than you? What percent are taller than you? (Example: If my height is 73 inches, then 20.86% of the relevant population is shorter. The other 79.14%, of course, is taller).

Be sure your name is on the **Week 5 Lab Assignment Template** (Word document), save it, and then submit it in the assignment dropbox on this page.
