Chapter 3, Problem 43PS

Thirty companies comprise the DJIA Just how big are these companies? One common method for measuring the size of a company is to use its market capitalization. which is computed by multiply:1g the number of stock shares by the price of a share of stock. On January 10, 2017. the market capitalization of these companies ranged from Traveler's $ 33.3

billion to Apple's $ 625.6 billion. The entire population of market capitalization values is stored in DowMarketCap.

a. Compute the mean and standard deviation of the market capitalization for this population of 30 companies

b. Interpret the parameters computed in (a).

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 + ...
