Description: According to a recent publication, the mean price of new mobile homes is $65,100. Assume a standard deviation of $7700. Let x denote the mean price of a sample of new mobile homes. a. For samples of 50 mobile homes, the mean and standard deviation o

(a) Compute the mean of the sampling distribution for the sample of 50 mobile homes. The mean of sampling distribution of the sample mean is obtained below as follows: Thus, the mean of sampling distribution of the sample mean is 65,100. Compute the standard deviation of the sampling distribution of the sample mean. The Standard deviation of sampling distribution of the sample mean is obtained below as follows: : The Standard deviation of sampling distribution of the sample mean is 1088.94 Therefore, the mean and standard deviation of all possible sample mean prices are $ 65,100 and $1088.94. (b) Compute the mean of the sampling distribution for the sample of 200 mobile homes. The mean of sampling distribution of the sample mean is obtained below as follows: Thus, the mean of sampling distribution of the sample mean is 65,100. Compute the standard deviation of the sampling distribution of the sample mean. The Standard deviation of sampling distribution of the sample mean is obtained below as follows: : The Standard deviation of sampling distribution of the sample mean is 544.47. Therefore, the mean and standard deviation of all possible sample mean prices are $ 65,100 and $544.47.

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 + ...
