Question 1172474: A random sample of 10 tins of oil filled in by an automatic machine gave the following weights in kg.
2.05, 2.01, 2.04, 1.98, 1.98, 1.96, 2.01, 1.99, 2.04, 2.02
can we accept at 5% level of significance, the claim that the average weight of the tin is 2kg
You can put this solution on YOUR website! The mean is 2.008
the sd is 0.030
t df=9 =0.008/0.030/sqrt(10)
=0.843
critical value is 2.262
fail to reject Ho at the 5% level.
Answer is yes, the claim of 2 kg average weight is correct.
