A machine being used for packaging seedless golden raisins has been set so that on average, 15 ounces of raisins will be packaged per box. The quality control engineer wishes to test the machine setting and selects a sample of 30 consecutive raisin packages filled during the production process. Their weights in ounces are recorded as follows:
15.2 15.5 15.2 15.8 15.3 15.0 15.3 14.5 14.8 14.6
15.0 15.2 15.8 15.9 15.6 15.4 15.7 159 15.4 15.1
152 15.5 15.6 15 815.7 159 156 15.3 15.1 15.2

Assume the observed sequence in which the data were collected is random and the population is normally distributed. To detemine if there is any evidence that the mean weight per box is different from 15 ounces at a level of significance alpha = 0.05, a hypothesis test can be performed.
A. State null hypothesis.
B. This is atail test.
C. Sample mean barX(2DP), sample standard deviation S =(4DP), and standard error of the mean =.
D. The test statistic =.(4DP).
E. The critical value =(4DP).
