Chapter 10, Problem 40CE, Listed below is the annual rate of return (reported in percent) for a sample of 12 taxable mutual

Using the .05 significance level, is it reasonable to conclude that the mean rate of return is more than 4.50%?

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...

Consider the following information: Net working capital/total assets = 0.9 Retained earnings/total earnings = 0.15 EBIT/total assets = 1.1 MV of equity/BV of total liabilities = 2 Sales/total assets = 2.5 Required: Compute the Z-score. Based on the calculation, explain whether there is a likelihood of financial distress?

Using the small model estimated above, what is the predicted percent boosted for: 1. A poor, primarily Republican county, located in the Midwest, with a mean educational level of 13 years? 2. A relatively elderly county, whose majority of registered voters are Democrats, with a mean educational level of 12 years?

1.Based on these sample data, is there a statistically significant relationship (at the .05 level) between whether one enters the hospital with lung cancer (vs. something else) and the number of cigarettes one smokes? What justifies this conclusion?
