Question
A coffee packaging plant claims that the mean weight of coffee in its
containers is at least 32 ounces. A random sample of 15 containers were
weighed and the mean weight was 31.8 ounces with a sample standard
deviation of 0.48 ounces. At the 0.01 significance level, test the claim
that the mean weight is at least 32 ounces. Assume a normal distribution
and complete the test below. Remember, since this is a study of the mean,
use the t-distribution
Ho; p> 32
HA: µ < 32
The critical value is
(round to 3 decimals)
The test statistic is
(round to 3 decimals)
Does the data support or not support the claim (type in support or does
not support)
