Find the distribution: a. b. c. d. e. f. following probabilities‚ the random variable Z has standard normal P (0< Z < 1.43) P (0.11 < Z < 1.98) P (-0.39 < Z < 1.22) P (Z < 0.92) P (Z > -1.78) P (Z < -2.08) 2. Determine the areas under the standard normal curve between –z and +z: ♦ z = 0.5 ♦ z = 2.0 Find the two values of z in standard normal distribution so that: P(-z < Z < +z) = 0.84 3.

Chapter 158 Distributions to Shareholders: Dividends and Repurchases ANSWERS TO END-OF-CHAPTER QUESTIONS 158-1 a. The optimal distribution policy is one that strikes a balance between dividend yield and capital gains so that the firm’s stock price is maximized. b. The dividend irrelevance theory holds that dividend policy has no effect on either the price of a firm’s stock or its cost of capital. The principal proponents of this view are Merton Miller and Franco Modigliani (MM). They

_____ 1. What is mean‚ variance and expectations? Mean - The mean of a discrete random variable X is a weighted average of the possible values that the random variable can take. Unlike the sample mean of a group of observations‚ which gives each observation equal weight‚ the mean of a random variable weights each outcome xi according to its probability‚ pi. The mean also of a random variable provides the long-run average of the variable‚ or the expected average outcome over many observations

perform a distribution function. The distribution function is vital to the economic well-being of society because it provides the goods and services desired by the consumer. Economists often describe the value of distribution in terms of ownership‚ place‚ and time utility. The marketer contributes to the product’s value by getting it to the right place at the time the consumer wants to buy it and by providing the mechanism for transferring ownership. Firms that do not perform the distribution function
