A laboratory in Oregon is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 150 healthy residence has a mean chloride level of 104 mEq /L. If it is known that the chloride levels in healthy individuals residing an organ to have a standard deviation of 38 mEq/L, A laboratory in Oregon is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 150 healthy residents has a mean chloride level of 104 mEq/L. If it is known that the chloride levels in healthy individuals residing in Oregon have a standard deviation of 38 mEq/L, find a 99% confidence interval for the true mean chloride level of all healthy Oregon residents.

A laboratory in Oregon is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 150 healthy residence has a mean chloride level of 104 mEq /L. If it is known that the chloride levels in healthy individuals residing an organ to have a standard deviation of 38 mEq/L,

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 + ...
