A. A beverage bottling company labels a product as having a mean volume of 16 oz. It is important to the company and consumers that the volume of each beverage is as close to 16 oz as possible. A quality control analyst randomly selects 45 beverages and finds that the mean volume is 16.3 oz, and the standard deviation is 0.8 oz. The company will need to adjust the bottling procedures if evidence exists that the mean volume of all beverages differs from 16 oz. Is this enough evidence at α=.10 to conclude that the mean volume of all beverages differs from 16 oz? What are the hypotheses of the test? B.

Question

A beverage bottling company labels a product as having a mean volume of 16 oz. It is important to the company and consumers that the volume of each beverage is as close to 16 oz as possible. A quality control analyst randomly selects 45 beverages and finds that the mean volume is 16.3 oz, and the standard deviation is 0.8 oz.

The company will need to adjust the bottling procedures if evidence exists that the mean volume of all beverages differs from 16 oz. Is this enough evidence at α=.10 to conclude that the mean volume of all beverages differs from 16 oz?

What are the hypotheses of the test?

The test statistic is calculated to be 1.72. What is the p-value of the test? Round final answer to 4 decimal places.

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 + ...
