Question

The issues surrounding the levels and structure of executive compensation have gained added prominence in the wake of the financial crisis that erupted in the fall of 2008. Based on the 2006 compensation data obtained from the securities and exchange commission (SEC) website, it was determined that the mean and the standard deviation of the compensation for the 500 paid CEOs in publicly traded U.S. companies are $10.32 million and $9.78 million, respectively. An analyst randomly choses 32 CEO compensations for 2006.

Is it necessary to apply the finite population correction factor? Explain.
Is the sampling distribution of the sample mean approximately normally distributed? Explain.
Calculate the expected value and the standard error of the sample mean.
What is the probability that the sample mean is more than $12 million?
What is the probability that the sample mean is between $10 million to $12 million?

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 + ...
