g. Thus, the final conclusion is that ...
The data suggest that the population
mean amount of time to assemble the
Meat Man barbecue is not significantly
higher than 9 at a = 0.05, so there is
statistically insignificant evidence to
conclude that the population mean
amount of time to assemble the Meat
Man barbecue is higher than 9.
The data suggest the population mean
is not significantly higher than 9 at a =
0.05, so there is statistically
insignificant evidence to conclude that
the population mean amount of time to
assemble the Meat Man barbecue is
equal to 9.
The data suggest the populaton mean is
significantly higher than 9 at a = 0.05,
so there is statistically significant
evidence to conclude that the
population mean amount of time to
assemble the Meat Man barbecue is
higher than 9.

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 + ...
