(b)	Determine the type of test statistic to use.
	▼(Choose one)
(c)	Find the value of the test statistic. (Round to three or more decimal places.)

(e)	At the 0.05 level of significance, can we conclude that the true mean discharge differs from 9 ounces?
Yes No

A coin-operated drink machine was designed to discharge a mean of 9 ounces of coffee per cup. In a test of the machine, the discharge amounts in 18 randomly
chosen cups of coffee from the machine were recorded. The sample mean and sample standard deviation were 8.84 ounces and 0.25 ounces, respectively. If we
assume that the discharge amounts are normally distributed, is there enough evidence, at the 0.05 level of significance, to conclude that the true mean
discharge, u, differs from 9 ounces?
Perform a two-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of
formulas.)
