The Centers for Disease Control developed the Youth J Risk Behavior Surveillance System (YRBSS) to monitor six categories of priority health risk behaviors among youth: behaviors that contribute to unintentional injuries and violence; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases; unhealthy dietary behaviors; and physical in activity. A multi stage sample design is used to produce representatives samples of students in grades 9 to 12, who then fill out a questionnaire on these behaviors.The data below are for the question “Did Not Use a Condom during Last Sexual Intercourse?” The two-way table of grade and condom usage includes only students who were currently sexually active.Here are the results:

Describe the most important differences between condom usage and grade. Is there a significant overall difference between the proportions who used condoms in the different grades?

The response time in milliseconds was determined for three different types of circuits in an electronic calculator. The results are recorded in table:

(a) What is the value of LSD? Use α=0.01.
Round your answer to two decimal places (e.g. 98.76).

(b) Apply Fisher's LSD method with α=0.01 and state which circuit type differs or circuit types differ.

(c) What is the absolute value of difference between means for circuits 1 and 3?
Round your answer to one decimal place (e.g. 98.7).

(d) Estimate the standard error for comparing the means using the graphical method.
Round your answer to three decimal places (e.g. 98.765).

How much time do Americans living in or near cities spend waiting in traffic, and how much does waiting in traffic cost them per year? The data set given includes this cost for 31 cities. For the time Americans living in or near cities spend waiting in traffic and the cost of waiting in traffic per year:

a. Compute the mean, median, first quartile, and third quartile.

b. Compute the range, interquartile range, variance, standard deviation, and coefficient of variation.

c. Construct a boxplot. Are the data skewed? If so, how?

d. Compute the correlation coefficient between the time spent sitting in traffic and the cost of sitting in traffic.

e. Based on the results of (a) through (c), what conclusions might you reach concerning the time spent waiting in traffic and the cost of waiting in traffic.

An employee of a small software company in Minneapolis bikes to work during the summer months. He can travel to work using one of three routes and wonders whether the average commute times (in minutes) differ between the three routes. He obtains the following data after traveling each route for one week.

a-1. Construct an ANOVA table. (Round intermediate calculations to at least 4 decimal places. Round "SS", "MS", "p-value" to 4 decimal places and "F" to 3 decimal places.)

ANOVA
Source of Variation   SS   df   MS   F   p-value
Between Groups                  
Within Groups                  

a-2. At the 1% significance level, do the average commute times differ between the three routes. Assume that commute times are normally distributed.

• Yes since the p-value is less than significance level.
• No  since the p-value is less than significance level.
• No  since the p-value is not less than significance level.
• Yes  since the p-value is not less than significance level.

b. Use Tukey’s HSD method at the 1% significance level to determine which routes' average times differ. (You may find it useful to reference the q table). (If the exact value for n_T − c is not found in the table, use the average of corresponding upper & lower studentized range values. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

Population Mean Difference   Confidence Interval   Do the average times differ?
μRoute 1 − μRoute 2 [       ,       ]  
μRoute 1 − μRoute 3 [       ,       ]  
μRoute 2 − μRoute 3 [       ,       ]  

Suppose an unrelated 82-year-old man, 72-year-old woman and 77-year-old man are selected from a community.

What is the probability that exactly one of the three people has Alzheimer's disease?

Select one of the Healthy People 2020 objectives and identify how biological risk (including age-related risk), environmental risk (including economic risk), and behavioral risk contribute to family health risks for that objective. Give examples.

2. Identify three public health problems in your community and discuss the implications of these problems for the health of families. How did you arrive at your conclusions?

Was it ethical for the search engines to comply fully with the DOJ subpoena discussed in the case?

"The Wall Street Journal article was referring to January 19, 2006, when the Department of Justice subpoenaed Google, Microsoft, Yahoo, and AOL for data on user queries submitted to their online search engines and a random sample of one million indexed web addresses (Mohammed, 2006). The Department of Justice sought to use this data to combat child pornography. "
