    ## 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, ฮฑ = .05]

    ### Calculations

    [Calculate the sample mean and standard error.]

    [Determine the appropriate test statistic, then calculate the test statistic. Note:ย This calculation is (mean โ€“ 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.]

    Detailed Explanation: Area of a Triangle FormulaThe area of any triangle can be calculated using the following formula:Area = ยฝ ร— base ร— heightOr written another way:Area = (base ร— height) รท 2 Given Information- Base (b)= 10 centimeters- Height (h)= 6 centimeters Step-by-Step CalculationStep 1:Multiply the base by the height- base ร— height = 10 cm ร— 6 cm = 60 cmยฒStep 2:Divide the result by 2 (or multiply by ยฝ)- 60 cmยฒ รท 2 = 30 cmยฒArea = 30 square centimeters (cmยฒ)โ€ข Why This Formula WorksThe formula works because:- A rectangle with the same base and height would have area = base ร— height- A triangle is exactly half of that rectangle (if you cut a rectangle diagonally)- Therefore, the triangle's area is half of the rectangle's areaโ€ข Visual Representation * /| / | height = 6 cm / | / | /___ |____ base = 10 cmThe height must be the perpendicular distance from the base to the opposite vertex (not the slanted side length).So the final answer is 30 cmยฒ ย shorten it and make it simple

    **_Instructions:_** Click on the link below to reply toย the givenย prompt. Then respond to at least two of your classmates' posts as described below.

    **_Prompt:_** In Section 4.4, we discussed an example with the Law of Forgetting. It states that if a task is learned at a performance levelย , then after a time interval
    _t_ the performance level
    _P_ satisfiesย ย where
    _c_ is a constant that depends on the type of task and
    _t_ is measured in months. We then solved for
    _P_ to getย . Use this to respond to the following.

    1. If your performance level is 80 and c = 0.9, what score would you expect to get on a similar task after 3 months?

    2. If your performance level is 80 and c = 0.1, what score would you expect to get on a similar task after 3 months?

    3. The expression โ€œjust like riding a bikeโ€ is often used to describe something that comes second nature and should be easy to do. Based on parts (1) and (2), would you expect the value of
    _c_ย to be closer to 0 or closer to 1 for the task of riding a bike? Justify your answer.

    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.โ€ฏAdd these heights to the Week 5 Lab Template along with the 10 provided by your instructor.
    3. Determine the mean and standard deviation forโ€ฏthe 20 values (your instructor's 10 from Step 1A above plus your 10) by using theโ€ฏ**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 theโ€ฏ20โ€ฏvalues? 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:โ€ฏsystematic, 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**โ€ฏfor the following:

    1. Use theโ€ฏ**Empirical Ruleโ€ฏtab** from the spreadsheet. Then, determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms of theโ€ฏ20 heightsโ€ฏin 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:โ€ฏIf 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**ย (Word document), save it, and then submit it in the assignment dropbox on this page.

    7. FunTime Carnival wishes to increase the height of their drop-tower attraction to 100 meters,
    expecting that the additional height will attract more customers. However, state regulations
    insist that the rideโ€™s average free-fall speed may not exceed 20m/s. Supposing that the rideโ€™s
    height above ground after ๐‘ก seconds is modeled by ๐‘ (๐‘ก) = โˆ’4.9๐‘ก + 100, determine if FunTime
    Carnival is behaving ethically with respect to state regulations in their attempt to increase
    profit.
