Problem 6-21 (Algorithmic)

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).

Year Percentage of Adults Who Smoke
1 22.7
2 21.9
3 21.2
4 20.8
5 20.8
6 20.2
7 19.3
8 20.6
9 20.6
10 19.8
11 18.9
  1. e simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series. Do not round your interim computations and round your final answers to three decimal places. For subtractive or negative numbers use a minus sign. (Example: -300)

    y-intercept, b0 =

    Slope, b1 =

    MSE =
  2. One of OSH’s goals is to cut the percentage of U.S. adults who were users of tobacco to 12% or less within nine years of the last year of these data. Does your regression model from part (b) suggest that OSH is on target to meet this goal?



    Use your model from part (b) to estimate the number of years that must pass after these data have been collected before OSH will achieve this goal. Round your answer to the nearest whole number.

Problem 4: Teen smoking According to a report published by the Centers for Disease Control and Prevention, about 20 percent of high school students currently use a tobacco product. This number of down from 23 percent in 2014. (https://www.cdc.gov/tobacco/data_statistics/fact_sheets/youth_data/tobacco_use/index.htm). We would like to conduct a study to evaluate high school students’ attitudes toward scenes of smoking in the movies. Suppose you randomly select students to survey them on their opinion about this question. a) What is the probability that none...

Reducing Health Disparities In 2011, the Centers for Disease Control and Prevention (CDC) published the first CDC Health Disparities and Inequalities Report (CHDIR). This report examined health disparities in the United States associated with various characteristics, including race/ethnicity, sex, income, education, disability status, and geography. Among other recommendations, the 2011 CHDIR emphasized the need to address health disparities with a dual intervention strategy that focuses on populations at greatest need and improves the health of the general population by making...

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...

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...
