You've just unboxed a new board game by legendary creator Stefan Feld. In the game, you roll a seven-sided, fair die with 4 red faces, 2 green faces, and 1 blue face. Your roll dictates how much gold you receive for rolling: red gives 1 gold, green gives 2 gold, and blue gives 4 gold.
a. Define a random variable for this setting, state the support, and find its probability model.
b. Find the expected value and variance of your random variable.
c. Suppose you have two special cards that can be applied after your roll. Card A triples your gold, while Card B increase the gold by 4. You will either apply Card A and then Card B, or vice versa. Write an expression using your random variable for each application strategy, and then decide which you should use by finding the expected value and standard deviation of each approach.

Passwords, red heads, and a z test: The BBC reported that red-haired women were more likely than others to choose strong passwords (Ward, 2013). How might a researcher study this? Computer scientist Cynthia Kuo and her colleagues conducted a study in which they gave passwords a score, with higher scores going to passwords that are not in “password crack dictionaries” that are used by hackers, that are longer, and that use a mix of letters, numbers, and symbols (2006). They found a mean score of 15.7 with a standard deviation of 7.3. For the purposes of this exercise, treat these numbers as the population parameters. Based on your knowledge of the z test, explain how you might design a study to test the hypothesis that red-haired women create stronger passwords than others.

We looked at various strategies to increase involvement for relatively boring or routine purchases. Is it a good idea for marketers to try to get us “excited” about everything we buy, or should they just accept that many of the things we buy are purely functional?
Explain your response in detail and give an example of a routine product you have purchased based on marketing.

Question One
Much debate exists within the literature about leadership and
management. Kotter (1990:103)
argues that management and leadership are “two distinctive and
complementary systems of
action” and that the former involves coping with complexity, while
the latter involves coping
with change.
1.1 Discuss in detail, with the use of examples, the fundamental
differences between the
concept of leadership versus management.
1.2 Evaluate in detail, with the use of practical examples, the
advantages and disadvantages
of a transformational leader.
1.3 Discuss in detail, with the use of practical examples, FOUR (4)
management styles and
the potential impact each style may have on a business.
