QuestionAt a water bottling factory, a machine is supposed to put 2 liters of water into the bottles. After an overhaul, management thinks the machine is no longer putting the correct amount of water in. They sample 20 bottles and and find an avg of 2.10 L of water with standard deviation of 0.33 L . Test the claim at 0.01 level of significance.

Studdy Solution
Make a decision:
Since the calculated t-statistic 1.3551.355 is less than the critical value 2.8612.861, we fail to reject the null hypothesis.
Conclusion: There is not enough evidence at the 0.01 level of significance to conclude that the machine is putting a different amount of water than 2 liters.
