(Source: Centers for Disease Control, www.cdc.gov)
Approximate the interval(s) over which the number of new AIDS cases among adolescents 20-24 yr increased.
Approximate the interval(s) over which the number of new AIDS cases among adolescents decreased.
How many turning points does the graph show?
Based on the number of turning points, what is the minimum degree of a polynomial function that could be used to model the data? Would the leading coefficient be positive or negative?

- Suppose at your university you are asked to find the relationship between weekly hours spent studying (study) and weekly hours spent working (work). Does it make sense to characterize the problem as inferring whether study “causes” work or work “causes” study?

- The librarian at a local school collected data on the number of students using the library after school each week during the first 22 weeks of school. The librarian counted the number of students in the library each day and then calculated the total for each week. The weekly totals were plotted in a graph and then a trend line was fit to the data. Students in the Library 600 500 400 300 200 100 5 10 15 20 25 Week Number For which week does the trend line underpredict the number of students using the library by the greatest amount? A week 3 B week 5 C week 10 D week 22 Number of Studentsarrow_forwardEnteroliths are calcifications that form in the gut of a horse. The stones can cause considerable morbidity and mortality. A study was conducted to investigate factors such as diet and environment that may be related to the formation of enteroliths. The study contained 62 horses with enteroliths (cases, the left graph) and 75 horses without (controls, the right graph). The graph below contains side-by-side boxplots of ages for cases and controls. Which of the following is true about these groups. Age 30 25 20 15 10 5 сл case enteroliths control=no enteroliths Panel variable: Diagnosis Box plot of age by diagnosis case O Based on the boxplots, the median age for cases and controls are both approximately 13. O Based on the boxplots, the median age for cases and controls are such that the cases are older and have a larger median. O Based on the boxplots, the median age for cases and controls cannot be determined from the plot given. O Based on the boxplots, the median age for cases and…arrow_forwardOver the past 40 years, the percentage of homes in the United States with smoke detectors has risen steadily and has plateaued at about 96% as of 2015.† With this increase in the use of home smoke detectors, what has happened to the death rate from home fires? Suppose the following contains 17 years of data on the estimated percentage of homes with smoke detectors and the estimated home fire deaths per million of population. Percentage ofHomes withSmoke Detectors Home Fire Deathsper Millionof Population 0.52 22.8 0.69 20.7 0.76 17.2 0.78 20.4 0.79 19.3 0.84 18.8 0.83 17.5 0.87 16.1 0.88 13.5 0.90 14.3 0.92 14.2 0.94 12.9 0.95 10.8 0.96 10.8 0.97 10.1 0.96 8.3 0.96 8.0 (a) Do you expect a positive or negative relationship between smoke detector use and deaths from home fires? Why or why not? We would expect there would be a ---Select--- negative positive relationship between smoke detector use and deaths from home fires. As more households have…arrow_forward
