Assignment 10 Answers 1. The return of any asset is the increase in
... Geometric average return = .1480 or 14.80% Remember that the geometric average return will always be less than the arithmetic average return if the returns have any variation. 21. To calculate the arithmetic and geometric average returns, we must first calculate the return for each year. The return ...

Chapter 6: Continuous Probability Distributions
... Before looking at the process for finding the probabilities under the normal curve, it is somewhat useful to look at the Empirical Rule that gives approximate values for these areas. The Empirical Rule is just an approximation and it will only be used in this section to give you an idea of what the ...

Solutions to the Exercises
... (b) The estimate for a female is 89/(89 16) = 0.85. (c) Since the number 0.85 is greater than the number 0.71, the experiment has provided some evidence to support the hypothesis that people are more helpful to females than to males. However, two questions arise. First, is the difference between the ...
