Question

Cost of Building a Home According to the National Association of Home Builders, the average cost of building a home in the Northeast is $117.91 per square foot. A random sample of 42 new homes indicated that the mean cost was $124.55 and the standard deviation was $15 . Can it be concluded that the mean cost differs from $117.91 , using the 0.05 level of significance?

A. State the hypotheses and identify the claim with the correct hypothesis.

H0	:	μ	▼(Choose one)	$	▼(Choose one)
H1	:	μ	▼(Choose one)	$	▼(Choose one)

This hypothesis test is a ▼(Choose one) test.

B. Compute the test value. Always round z score values to at least two decimal places. z =

C. Find the P -value. Round the answer to at least four decimal places. P -value =

D. Make the decision.

▼Reject the null hypothesis.

E. Summarize the results.

There is ▼not enough evidence to support the claim that the average weight loss of a newborn baby is less than

7 ounces.

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 + ...
