Question: 5 ferric chloride is used as a flux in some...

Question details

5. Ferric chloride is used as a flux in some types of extraction metallurgy processes. This material is shipped in containers, and the container weight varies. It is important to obtain an accurate estimate of mean container weight. Suppose that from long experience a reliable value for the standard deviation of flux container weight is determined to be 3 lb. The standard weight of a container is 50 lbs. You are concerned that it may be as high as 50.6 lbs., however. If you test using a sample size of n 10, what is the probability of accepting the null hypothesis Ho 50 when the weight is actually 50.6 lbs. ( .-0.05)? Assume weight is normally distributed.
