Question

A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces, the company wants the packages to contain a mean of

8.17

ounces so that virtually none of the packages contain less than 8 ounces. A sample of

packages is selected periodically, and the packaging process is stopped if there is evidence that the mean amount packaged is different from

8.17

ounces. Suppose that in a particular sample of

packages, the mean amount dispensed is

8.161

ounces, with a sample standard deviation of

0.048

ounce. Complete parts (a) and (b).

a. Is there evidence that the population mean amount is different from

8.17

ounces? (Use a

0.10

level of significance.)

Find the critical values of the t distribution

Determine the p-value and interpret its meaning.

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 + ...
