DATA: Hypothesis

Human Body Temperature: What is Normal?

The record for the human body temperature, established more than a centuries ago, is 98.6 F^o. Testing the claim, the University of Maryland'sVaccine Centergathers data of 130 healthy adults (65 males, 65 females). Work with the calculated statistics and test at 5% level of significance, if the human body temperature of healthy adult is 98.6 F^o.

Reminders.

• Before you begin, check your previously found statistics are correct.
• DO NOT COPY and PASTE questions.
• Label each answer corresponding number (letter) in the question.
• Enter all answers and embed the image in the edit box. NO credit for attached files.

Discussion Post: Use sentences to answer all questions. Mathematical equations are sentences.

1. In a sentence

(a) state the mean for the sample of 130 healthy adults. (b) state the sample standard deviation for 130 healthy adults.

2. Write a mathematical statement of hypothesis in equation form.

H_o: ________________________________

H_a: ________________________________

3. a) Calculate the standardized test statistic (three decimal places). Write answer as an equation. Explain or show calculations.

b) For the standardized test statistic found in 3(a), use a calculator or Excel or StatCrunch to find P-value. Round answer to eight or nine decimal places.

P-value = _____________________________________

4. UseHypothesis Test Generator to find P-value. Embed the image of the graph in the edit box. No file attachment of an image.

(a) Click on Hypothesis Test GeneratorLinks to an external site.. https://www.imathas.com/stattools/norm.html Review the posted information.

(b) Enter the statistics in the required fields.

(c) Use width 400, height 150. Select shade P-value. Click the "Draw Here" button. You should see the graph. Observe shaded P-value on the graph.

(d) Paste image in discussion board. Follow the instructions for copy and paste. Embed an image: Right-click on the graph and Copy and then Paste the image in the discussion page.

5. Compare P-value in 3(b) with the observed P-value on the graph. Explain and use statistical terminology.

6. Write a mathematical statement of comparison between P-value and given level of significance. (This is an inequality statement.)

7. Based on the inequality statement in step 6, write a one sentence conclusion.

8. Interpret meaning of conclusion with respect to the given problem. Follow the language in in model examples from the eBook.

9. In a separate paragraph, explain what you learned.
