Read Case Activity: A Social Media Campaign for Yogurt Program on page 244.

Answer the questions in the Writing Prompt section and provide your opinion on the use of social media (based on the chapter) for the public relations activities part of their marketing plan. Participate in the discussion on Social Media with someone else in the course. This is page 244: The discussion on the previous pages examined ways in which an individual can formulate persuasive messages. The ability to use these techniques often leads to charges that public relations practitioners have great power to influence and manipulate people. In reality, the effectiveness of persuasive techniques is greatly exaggerated. Persuasion is not an exact science, and no surefire way exists to predict that people will be persuaded to believe a message or act on it. If persuasive techniques were as refined as the critics say, all people might be driving the same make of car, using the same soap, and voting for the same political candidate. This doesn’t happen because several variables intervene in the flow of persuasive messages. Elihu Katz says the two major intervening variables are selectivity and interpersonal relations; these are consistent with the limited-effects model of mass communication.

For purposes of discussion, the limitations on effective persuasive messages can be listed as:

(1) lack of message penetration,

(2) competing messages,

(3) self-selection, and

(4) self-perception.

Because the database server can cache and reuse ___________________ statements, they are more efficient than regular SQL statements.

When you work with a result set, the ____________ identifies the current position in the result set.

You use the __________________ class to work with data returned from a SQL query.

What does the invoices result set contain after the code that follows is executed?
String sql = "SELECT InvoiceDate, InvoiceTotal "
           + "FROM Invoices WHERE InvoiceTotal > ?";

Problem 31. Calculate the expected value and variance of X for each of the following scenarios.

1. X = {0, 1} where each has equal probability. (A coin flip)

2. X = {1, 2, 3, 4, 5, 6} where each has equal probability. (A die roll)

3. X = {0, 1} with f(0) = 1/3 and f(1) = 2/3.

4. X = B(3, 0.35). (Use info from Problem 26.)(Problem 26. Let X = B(3, 0.35). Calculate each f(k) and the sum X 3 k=0 f(k).)
