You are part of a research team in the newly formed University of California Center for Climate, Health and Equity. The team is interested in studying whether California adults experience levels of inflammation from wildfire smoke that are different compared to the US as a whole. Previous studies reported an average c-reactive protein (CRP) (a measure of systemic inflammation) of 8.2 mg/L among US adults. You obtain a sample of 100 Califor- nia adults and find that their average CRP is 9.0 with a sample standard deviation of 2.0 mg/L. 1.1 State the null and alternative hypotheses using mathematical notation in the context of this question. Но : НА: 1.2 Calculate the 95% confidence interval for the average CRP for California adults. Assume a critical value of 1.98 and round your answer to 2 decimal places. work:
The automated data collection system for a manufacturing process will record data for 25,000 parts per day. Assume that, when stable, a certain process will operate with a nonconformance rate of 37.6 NCPPM (nonconforming parts per million). If the nonconformance rate per day is to be monitored using a control chart, what type of chart would be used? Choose a P, U, or X-Bar/S Charts, and explain in a few words.
Anemia (low healthy blood cells or hemoglobin) has an important role in exercise performance. However, the direct link between rapid changes of hemoglobin and exercise performance is still unknown. A study investigated 18 patients with a blood disorder (beta-thalassemia). Participants in the study performed an exercise test before and the day after receiving a blood transfusion. Data are given in the table. HB = Hemoglobin RER = Respiratory exchange ID Change in HB Obese RER > 1.1 ratio No No 1 -1.4 No -1.5 No Yes No Yes 3 -2 No 4 -2.1 No -1.9 Yes Yes No -1.6 -1.8 -0.8 6 7 No Yes No Yes 8 9. -1 No No -1.2 No Yes 10 11 No No -0.8 -1.5 12 Yes No No Yes 13 14 -1.4 -2.6 -1.7 No No Yes Yes 15 Yes No Yes Yes 16 -2.6 No 17 18 -2.7 -1.5 No
In an observational study it was found that people who had received the flu shot this year had better blood pressure readings, on average, than people who did not. Can it be claimed that the flu shot is the cause of the lower overall blood pressure? Why or why not?
Examine and report on the process of how a researcher would collect data for this study; also discuss the ethical clearanceprocess.
Benzene is a pollutant that, according to studies, can be associated with health problems. Benzene is found in air, water, and soil and comes from both industrial and natural sources. Benzene levels in indoor air are generally higher than outdoors. The main source of benzene in indoor air appears to be tobacco smoke, thus the combustion of tobacco is a major source of pollution. Benzene levels are measured in a random sample of 36 bars in a city, obtaining an average benzene level of 19.2 mg / m3, with a standard deviation of 2.1 mg / m3. Estimate the mean benzene level in bars in this city using a 95% confidence interval.

Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Boletus pinicola and published the results in the paper “Influence of Some Factors in Toxicity and Accumulation of Cd from Edible Wild Macrofungi in NW Spain” (Journal of Environmental Science and Health, Vol. B33(4), pp. 439–455). A hypothesis test is to be performed to decide whether the mean cadmium level in Boletus pinicola mushrooms is greater than the government’s recommended limit. Hypothesis tests are proposed. For each hypothesis test,a. determine the null hypothesis.b. determine the alternative hypothesis.c. classify the hypothesis test as two tailed, left tailed, or right tailed.
An auto-parts store offers a fuel additive that claims to increase a vehicle’s gas mileage. The additive is poured into a vehicle’s gasoline tank after the tank is filled. To measure the claim, two methods to collect data are proposed.

A study is planned to investigate risk factors for sudden cardiac death. A cohort of men and women between the ages of 35 and 70 are enrolled and followed for up to 20 years. As part of the study, participants provide data on demographic and behavioral characteristics, they also undergo testing for cardiac function and provide a blood samples to assess lipid profiles and other biomarkers. A new measure of inflammation is hypothesized to be related to sudden cardiac death. What study design is most appropriate to assess the association between the new biomarker and sudden cardiac death? Are there any assumptions about cardiac death that we must assume for this study type? Indicate the study type's specific strengths and weaknesses.
