A manufacturing company produces steel housings for electrical equipment. The main component part is a steel trough that is made out of 14-gauge steel coil. Steel troughs are produced using a 250-ton progressive punch press that puts two 90° forms in the flat steel to make the trough. The distance from one side of the form to the other is critical for weatherproofing.

Question a) For α=.05, is there sufficient sample evidence that the true mean width of the troughs is greater than 8.4 inches?

b) For α=.05, is there sufficient sample evidence that the true mean width of the troughs is less than 8.5 inches?

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 + ...
