There is a difference between public relations, known today as earned media, and advertising, also known as paid media. Both disciplines are important in the overall marketing campaign of a brand, whether it is a product, business, company, service, person, idea, or place. Social media has also become an important way to advertise and publicize anything.

Key Concept Snapshot: Advertising is paid media, meaning the marketer crafts and pays for the message that they want to present to the audience. The marketer controls the published or presented message. 

Key Concept Snapshot: Public relations is earned media, meaning the information being marketed through persuasive messaging is earned and the public develops its own opinions about the product, service, idea, and business and beyond. The marketer does not control the published or presented message.

There are several advantages to using both disciplines in crafting and marketing a message to sell products and services. To prepare for this assignment, do the following:

• To help you understand the difference between advertising and public relations, watch the following videos: 
• Reflect on these differences in your assignment. 

Create your assignment.

Scenario: Suppose you want to start an online business part-time. Include the following 3 main ideas in your 3–5-page assignment:

• What’s the difference between public relations and advertising? First, write about the differences between advertising (paid media) and public relations (earned media). Provide examples. 
• How would you advertise and publicize the business? Write about how you might approach advertising and public relations for a product of your choice. Explain your interpretation of the differences. 
• Market, message, and media: Now that you have considered, reviewed, and analyzed public relations and advertising, think about your market, message and media. Explain your different ideas about messages to advertise and publicize a product or business.

Q-3a. A sample of students from an introductory psychology class were polled regarding the number of hours they spent studying for the last exam. All students anonymously submitted the number of hours on a 3 by 5 card. There were 24 individuals in the one section of the course polled. The data was used to make inferences regarding the other students taking the course. Construct a 95% confidence interval estimate . Explain your findings so that your non-quantitave partner will understand them. Their data is below: (5 pts.)

Q-3b. A sample of Alzheimer's patients are tested to assess the amount of time (in minutes) in stage IV sleep. It has been hypothesized that individuals sufferering from Alzheimer's Disease may spend less time per night in the deeper stages of sleep. The number of minutes spent is Stage IV sleep is recorded for thirty patients (refer to sample data below of stage IV sleep over a 24 hour period). Compute a 95 percent confidence interval for this data. What does this information tell you about a particular individual's (an Alzheimer's patient) stage IV sleep? Explain your findings so that your non-quantitative partner will understand them. (5 pts.)

Q-3c. A large retail corportation plans to sample sales receipts of its meat department to estimate the average size (in dollars) of a customer purchase. Previous analysis suggest that the standard deviation of the purchase amount is approximately $50.72. In order to calculate a 95% confidence interval of the total width less than $6.50, how many sales receipts should the corportion include in the sample? Explain your findings so that your non-quantitative partner will understand them. (5 pts.)

Q-3d. A survey of 850 workers were asked how much they used the Internet at work. 578 said they used the internet within limits, and 255 said that they did not use the Internet within limits. Construct a 95% confidence interval estimate for the proportion of all workers who did not use the Internet within limits. Explain your findings so that your non-quantitative partner will understand them. (5 pts.)

Q-3e. You are the designer for your company's web site. You have data to indicate that the mean download time for the homepage is 5.8 seconds and that the standard deviation of download time is 2.1 seconds. If we assume that the download times are normally distributed, what percent of users will wait between 4 and 8 seconds for the homepage to download? Explain your findings so that your non-quantitative partner will understand them. (5 pts.)

Q-4a. You are the manager of a popular retail store. You want to determine whether the population mean wait time for customer to

check-out has changed in the past month from its previous population mean value of 4.25 minutes. From past experience, you 

can assume that the population is normally distributed with a population standard deviation of 1.6 minutes. You select a sample 

of 43 customer’s wait time to check-out during a one hour period. The sample mean is 4.75 minutes. Determine whether there 

is evidence at the 0.05 level of significance that the population mean wait time to check-out has changed in the past month from 

its previous population mean value of 4.25 minutes. Explain your findings utlizing information from the hypothesis test you 

conduct. (5 pts.)

Q-4b. You are the manager of a fast-food restaurant. Based on a sample of two-hundred fifty drive-through orders, you discovered that 

orders were filled correctly 86.5% of the time. In an effort to improve the amount of orders filled correctly, you developed a new 

process to fill orders. After sampling two-hundred fifty orders under this new process, the results reviled that 225 orders were 

filled correctly. At the 0.01 level of significance, can you conclude that the new process population proportion of orders filled 

correctly is higher than the proportion of orders filled under the old process? Explain your findings utilizing information from the

test you conduct. (5 pts.)
