Part 2 of 4
Measuring lung function: One of the measurements used to determine
the health of a person's lungs is the amount of air a person can exhale
under force in one second. This is called forced expiratory volume in one
second, and is abbreviated FEV₁. Assume the mean FEV₁ for 10-year-old
boys is 2.1 liters and that the population standard deviation is 6=0.4. A
random sample of 63 10-year-old boys who live in a community with high
levels of ozone pollution are found to have a sample mean FEV₁ of 1.97
liters. Can you conclude that the mean FEV₁ in the high-pollution
community is less than 2.1 liters? Use the a=0.10 level of significance and the
P-value method with the TI-84 calculator.

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 + ...
