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 + ...

Winter visitors are extremely important to the economy of Southwest Florida. Hoteloccupancy is an often-reported measure of visitor volume and visitor activity (naplesdaily news, March 22, 2012). Hotel occupancy data for February in two consecutiveyears are as follows.OccupancyCurrent Year Previous YearOccupied Rooms 1470 1458Total Rooms 1750 1800a. Formulate the hypothesis test that can be used to determine if there has been anincrease in the proportion of rooms occupied over the one-year period.b. What is the estimated proportion of hotel rooms occupied each year?c. Using a .05 level of significance, what is your hypothesis test conclusion? What is thep-value?d. What is the 95% confidence interval estimate of the change in occupancy for the oneyear period? Do you think area officials would be pleased with the results?

You come across Professor Cafferty's data set from his Master's thesis and realize that he has data on types of family support that 26 homosexual men had during young adulthood (about 18-25 years old).
