Question

The original data set is in the picture and the question parts needs to be answered as well for the original data set. Read and answer carefully and correctly.

Compute the mean, median, and mode for the data. Show your complete work.

(b) Compute a 5% trimmed mean for the data, and compare it with the mean computed in part (a). Does the trimmed mean more accurately reflect the general level of the daily rental costs?

If 5 will be added to each cost of condominiums, what will be the mean, median and mode?

If each cost of condominium will be added by 10 and multiplied by 2, what will be the mean, median and mode?

Leisure: Maui Vacation How
expensive is Maui? If you want a
vacation rental condominium (up to
four people), visit the Brase/Brase
statistics site, find the link to Maui,
and then search for
accommodations. The Maui News
gave the following costs in dollars per
day for a random sample of

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 + ...
