Studies have shown that people who are using safety equipment when engaging in an activity tend to take increased risks. Will risk taking increase when people are not aware they are wearing protective equipment and are engaged in an activity that cannot be made safer by this equipment? Participants in the study were falsely told they were taking part in an eye-tracking experiment for which they needed to wear an eye-tracking device. Eighty subjects were divided at random into two groups of 40 each, with one group wearing the tracking device mounted on a baseball cap and the other group wearing it mounted on a bicycle helmet. Subjects were told that the helmet or cap was just being used to mount the eye tracker. All subjects watched an animated balloon on a video screen and pressed a button to inflate it. The balloon was programmed to burst at a random point, but until that point, each press of the button inflated the balloon further and increased the amount of fictional currency a subject would earn. Subjects were free to stop pumping at any point and keep their earnings, knowing that if the balloon burst, they would lose all earnings for that round. The score was the average number of pumps on the trials, with lower scores corresponding to less risk taking and more conservative play. Here are the first 10 observations from each group.

Helmet: 3.67 36.50 29.28 30.50 24.08 32.10 50.67 26.26 41.05 20.56

Baseball Cap: 29.38 42.50 41.57 47.77 32.45 30.65 7.04 2.68 22.04 25.86

Compare the distributions for the two groups. How is wearing of a helmet related to the measure of risk behavior? Hint: Create side by side box and whisker plots.

A weight-lifting coach wanted to know whether weight-lifters can change their strength by taking a certain supplement. To answer this question, the coach randomly selected 8 athletes and gave them a strength test using a bench press. Thirty days later, after regular training using the supplement, they were tested again. The results were listed below. A test was conducted to determine whether weight-lifters can change their strength by taking a certain supplement. Assume the populations are normally distributed.

Athlete 1 2 3 4 5 6 7 8 Mean SD

Before 215 240 188 212 275 260 225 200 226.88 29.72

After 225 245 188 210 282 275 230 195 231.25 34.55

Difference -10 -5 0 2 -7 -15 -5 5 -4.38 6.55

1. What is the null hypothesis for this test?

2. What is the value of the standardized test statistic?

3. The p-value was 0.05. Suppose this test was conducted at α = 0.01. What can you conclude?

a. There is insufficient evidence to conclude that weight-lifters can change their strength by taking a certain supplement.

b. There is sufficient evidence to conclude that weight-lifters can change their strength by taking a certain supplement.

c. None of the above; this test is invalid.

4. Suppose the coach had incorrectly performed a two-sample t-test. In comparison to the correct analysis, which of the following regarding the test statistic would be true?

a. The test statistic is closer to 0

b. The test statistic is farther from 0

c. The test statistic does not change.

Healthy Lifestyles

The Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, is the government agency responsible for disease-related issues in the United States. The CDC coordinates efforts to counteract outbreaks of diseases and funds a variety of medical and health research studies. The CDC also serves as a central clearinghouse for health-related data.

The CDC conducts the annual Behavioral Risk Factor Surveillance Survey. The survey measures a whole series of lifestyle characteristics that relate to health and longevity, such as smoking and use of seat belts. The survey compiles data on a stateby-state basis. Not all states are surveyed.

The data set from the 1990 Behavioral Risk Factor Surveillance Survey is on the accompanying CD in the file named HEALTHY. All numbers are percentages, and asterisks indicate the missing data for that state.

Your task is to prepare a summary of these data. Your report is to be issued to major news organizations, such as the Associated Press, and will appear in major newspapers around the United States. For this reason, it would be inappropriate to use technical jargon in your report.

Your boss has suggested a few general ideas about what is likely to appeal to your target audience. As you study the data, you might find other things worth including.

Questions

1. Report any interesting (i.e., unexpected, humorous, or odd) differences between states.

2. Devise a weighted index of all seven lifestyle variables. The weighted index is to serve as an overall or composite measure of healthy lifestyles. Apply your weight to the states of Minnesota, Florida, and California as an example of what your weighted index shows.

3. Discuss any noteworthy limitations of the survey or data set.

answer the following questions based on the learning and your personal knowledge – with the concept of Best Practices at mind. Today, you are all marketing teams for your brand. You are working on the Promotion function:

1.How is your brand currently promoted (be specific)? Detail all of the ways (do some research) and show examples.

2.Create a new promotion strategy (using IMC principles) for the brand and choose a minimum of three tools in the promotion mix. Why did you choose these? What goals do they accomplish? How does this new IMC strategy fit with the Marketing Mix, Positioning, and Differentiation strategy for your company.

3. There was a quality problem a month ago and your brand has to recall all of the products made that day (10,000 items). Craft a Press Release and create a Public Relations strategy that fits with your IMC strategy while alerting customers to problem/solution.

4. Check out the company/brand’s website. Develop a detailed profile of consumers attracted to Web site and why. What are the primary methods used to drive traffic to the Web site? What is the value addition for the current or new customer base?

5. What social media Web site(s) does the company utilize? Social media objectives are listed in Chapter 22 on page 356. Identify the company’s primary social media objectives based on actual communications on its social networking site. Be sure to provide examples.

6. Compare the company’s social networking site with its official Web site. How does the content and language differ between the two sites?

7. What do you recommend that the company do to stay on top of current social media trends?

1) The source code must be well structured and include relevant comments like on the top lines version, date, and a brief description of what the program does.

2) . As you make changes you can add one line description of the changes and change the version # or add a version #
like version 1.0 and 1.1

3) Write a short report (not to exceed 100 words) that describes the work done, the input, and output when executing the program.

Lab 7   - Rectangle class-   (Lec. 7)

1.) Create a new project and

name it:    Rectangle

2.) Create the following 3 files:

• Rectangle.h
• Rectangle.cpp
• Source.cpp

3.) Write a program that produces

this output:

Rectangle.h

4.)In the Rectangle.h file, write a class specification for a Rectangle class.

            2 private data members:      _width (int) and _length (int)

            7 public member functions:

      Default constructor - Assigns ‘safe’ values to the data members.

      Descructor

      setWidth – An int value, passed from main(), is assigned to _width.

      setLength - An int value, passed from main(), is assigned to _length.

      getWidth – Returns the object’s width.

      getLength – Returns the object’s length.

      getArea – Calculates the area of the Rectangle object and returns the value.

Rectangle.cpp

5.) In the Rectangle.cpp file, write a function implementation for each function

prototype listed in the Rectangle class specification.

Source.cpp

6.)In main(), declare an object of Rectangletype, and name it:    tennisCourt

7.) In main(), declare three variables of double data type, and

                and name them:   width, length and area

6.) Prompt the user to enter a width and length (see output).

7.) Read in the user’s inputs and assign them to the data members of tennisCourt,

             by using the ‘set’ member functions.

8.)Then assign the tennis court’s width, length and area to variable in main() by

             using the ‘get’ member functions.

9.)Display the width, length, and area. (see output)
