A blogger claims that U.S. adults drink an average of 40 ounces (that's five 8-ounce glasses) of water per day. Researcherswonder if this claim is true, so they ask a random sample of 24 U.S. adults about their daily water intake. A graph of the datashows a roughly symmetric shape with no outliers.What are the appropriate hypotheses for a significance test in this setting?Ho : µ = 40, Ha : u + 40 where u = the true mean daily water intake that a U.S. adult drinks per day.Ho : µ = 40, Ha : µ < 40 where u = the true mean daily water intake that a U.S. adult drinks per day.Ho : u 2 40, Ha : µ < 40 where u = the true mean daily water intake that a U.S. adult drinks per day.O Ho : µ < 40, Ha : µ > 40 where u =the true mean daily water intake that a U.S. adult drinks per day.

The population must be approximately normal Construct a 90% confidence interval for the population mean length of time. (Round upper and lower bounds to 2 decimal places.) What does it mean to be "90% confident" in this problem? There is a 90% chance that the confidence interval contains the sample mean time. The confidence…
You collect information on a random sample of women and obtain estimates on vitamin D exposure. However, the results that you find are different than those conducted at another study site. Should you be concerned? Explain your answer using the concept of sampling variability
During the 1990s, the fatality rate for lung cancer was 80 per 100,000 people. After the turn of the century and the establishment of newer treatments and adjustment in public health advertising, a random sample of 10,000 people exhibits only six deaths due to lung cancer. Test at the 0.05 significance level whether that data are proof of a reduced fatality rate for lung cancer. b. Make the decision rule. (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.) c. Evaluate the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)
Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. Some governments have a safety limit for cadmium in dry vegetables at 0.56 part per million (ppm). A research team measured the cadmium levels in a random sample of edible mushrooms, where the hypothesis test is to decide whether the mean cadmium level in the sample is greater than the governments' safety limit. The null and alternative hypotheses are H0: μ=0.56 ppm, Ha: μ>0.56 ppm. Complete parts (a) through (e) below. d. Now suppose that the results of carrying out the hypothesis test lead to nonrejection of the null hypothesis. Classify that conclusion by error type or as a correct decision if in fact the mean cadmium level in that type of mushrooms equals the safety limit of 0.56 ppm. Choose the correct answer below. A. type I error B. correct decision because a true null hypothesis is not rejected C. correct decision because…

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
Low‑density lipoprotein, or LDL, is the main source of cholesterol buildup and blockage in the arteries. This is why LDL is known as "bad cholesterol." LDL is measured in milligrams per deciliter of blood, or mg/dL. In a population of adults at risk for cardiovascular problems, the distribution of LDL levels is normal, with a mean of 123123 mg/dL and a standard deviation of 4141 mg/dL. If an individual's LDL is at least 11 standard deviation or more above the mean, he or she will be monitored carefully by a doctor. What percentage of individuals from this population will have LDL levels 11 or more standard deviations above the mean? Use the 6868–9595–99.799.7 rule. (Enter your exact answer as a whole number.)
