Radon is a colorless, odorless gas that is naturally released by rocks and soils and may concentrate in tightly closed houses. Since radon is slightly radioactive, there is some concerm that it may be a health hazard. Radon detectors are sold to homeowners worried about this risk, but the detectors may be inaccurate. University researchers placed 30 radon detectors in a chamber where they were exposed to 105 picocuries per liter (pCi/l) of radon over 3 days. The sample average reading from the 30 radon detectors was 102.87 pCiA and the sample standard deviation was 4.9 pCiA.

Question 4 The National Institute of Mental Health published an article stating that in any one-year period, approximately 8.3% of American adults suffer from depression or a depressive illness. Suppose that in a survey of 2000 people in a certain city, 11.5% of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that city suffering from depression or a depressive illness is more than the 8.3% in the general adult American population. Test the relevant hypotheses using a 5% level of significance. Give answer to at least 4 decimal places. a. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: Select an answer? H₁: Select an answer? b. Based on the hypotheses, find the following: c. Test Statistic = d. p-value = e. Based on the above we choose to Select an answer f. The correct summary would be: Select an answer that the true proportion of people in that…

9 Question 4 A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips. Not every bag contains exactly the same weight. But if more than 16% of bags are over-filled then they stop production to fix the machine. They define over-filled to be more than 1 ounce above the weight on the package. The engineer weighs 129 bags and finds that 27 of them are over-filled. He plans to test the hypotheses Ho: p = 0.16 versus H:p> 0.16. What is the test statistic? Z = (Please round your answer to two decimal places if necessary.)
The national average SAT score is roughly 1500. We would like to see if the high school seniors who apply to Duke have higher than average SAT scores. We randomly sample 100 applicants' files and record their SAT scores. Which of the following is the correct set of hypotheses for this research question? Hint: think about how many samples we have data from. H0: μ = 1500; HA: μ ≠ 1500 H0: p = 1500; HA: p > 1500 H0: μ Duke= μ National; HA: μ Duke> μ National H0: x = 1500; HA: x > 1500 H0: μ = 1500; HA: μ > 1500
Problem 7 A new formulation of concrete has been designed for a particular building application. Naturally, the strength of concrete produced with the new formulation had to be tested for its strength capability. The compressive strength of 12 specimens were tested, as shown below. 2216 2281 2237 2263 2249 2318 2204 2255 2225 2275 2301 2295 a. With a simple histogram, draw conclusions about the normality of these observations. Assume normality regardless. b. Calculate a 95% confidence interval for mean compressive strength. c. Calculate a 95% confidence interval for standard deviation of compressive strength.
