Question

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 of all possible sample mean prices are $_________ and

$__________, respectively.

(Round to the nearest cent as needed.)

b. For samples of 200 mobile homes, the mean and standard deviation of all possible sample mean prices are $________and

$_________, respectively.

(Round to the nearest cent as needed.)

A researcher focusing on birth weights of babies found that the mean birth weight is 3372 grams (7 pounds, 6.9 ounces) with a standard deviation of 580
grams. Complete parts (a) through (c) below.
A. The group of all babies ever born
B. The number of babies born the year the research was performed
C. The group of all of the babies whose recorded weights were examined
D. The group of researchers
Choose the correct variable below.
A. The number of births per capita
B. The number of babies that were born
C. The accuracy of the measurements of baby birth weights
D. The weights of the babies at birth
b. For samples of size 250, find the mean u, and standard deviation o, of all possible sample mean weights.
(Type an integer or a decimal. Do not round.)

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 + ...
