d.Do second test





e.None of the above





What is the conclusion?







a.We are 95% confident that the average content of sacks of a powdered raw material is not equal to 50 kg.







b.We are 95% confident that the average content of sacks of a powdered raw material is less than 50 kg.







c.We are 95% confident that the average content of sacks of a powdered raw material is greater than 50 kg.







d.We are 95% confident that the average content of sacks of a powdered raw material is 50 kg.







e.None of the above








Test the hypothesis that the average weight of the sacks of a powdered raw material is 50 kg if the<br>contents of a random sample of 12 sacks are 50.2, 49.3, 50.1, 49.24, 49.37, 50.24, 49.09, 50.35, 49.08,<br>49.72, 50.21, and 49.67 kg. Use a 0.05 level of significance and assume the distribution of contents is<br>normal.<br>
