(b) What is the probability that none of them has a Chlamydia infection? (c) What is the probability that at least one of them has a Chlamydia infection? (d) What is the probability that at most one has a Chlamydia infection?

2. In 2016, the Centers for Disease Control and Prevention reported that 36.5% of adults in the United States are obese. A county health service planning a new awareness campaign polls a random sample of 750 adults living there. In this sample, 228 people were found to be obese based on their answers to a health questionnaire. Do these responses provide strong evidence that the 36.5% figure is not accurate for this region? Use a significance level of 5% to...

In 2012 the Centers for Disease Control and Prevention reported that in a sample of 4,349 African Americans 31% were Vitamin D deficient. A 90% confidence interval based on this sample is (0.30, 0.32). It is believed that among the general population of Americans 8% suffer from Vitamin D deficiency. Define the appropriate parameter and state the appropriate hypotheses for testing the claim that, among African Americans, Vitamin D deficiency occurs at a rate other than 8%. Does this confidence...

The Centers for Disease Control and Prevention Office on Smoking and Health (OSH) is the lead federal agency responsible for comprehensive tobacco prevention and control. OSH was established in 1965 to reduce the death and disease caused by tobacco use and exposure to secondhand smoke. One of the many responsibilities of the OSH is to collect data on tobacco use. The following data show the percentage of U.S. adults who were users of tobacco for a recent 11-year period (http://www.cdc.gov/tobacco/data_statistics/tables/trends/cig_smoking/index.htm)....

According to the Centers for Disease Control and Prevention (CDC), the mean weight of U.S. men of age 30–39 years old is191.802 pounds. Using the provided sample data file, conduct a one-sample ?-z-test of a mean to test whether the mean weight of men of age 30–39 years old who smoke daily is lower than191.802. Conduct the z-test at a significance level of α=0.05 to test the null hypothesis, H0:μ=191.802, against the alternative hypothesis, H1:μ<191.802, where ?μ represents the mean...
