Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected and the alcohol content of each bottle is determined. Let u denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (7.8, 9.4). (a) Consider the following statement: There is a 95% chance that is between 7.8 and 9.4. Is this statement correct? Why or why not? (b) Consider the following statement: We can be highly confident that 95% of all bottles of this type of cough syrup have an alcohol content that is between 7.8 and 9.4. Is this statement correct? Why or why not? (c) Consider the following statement: If the procedure of selecting a sample of size 50 and then computing the corresponding 95% interval is repeated 100 times, approximately 95 of the resulting intervals will include u. Is this statement correct? Why or why not?

Question
Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected and the alcohol content of each bottle is determined. Let μ denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (7.8, 9.4). (a) Consider the following statement: There is a 95% chance that μ is between 7.8 and 9.4. Is this statement correct? Why or why not? (b) Consider the following statement: We can be highly confident that 95% of all bottles of this type of cough syrup have an alcohol content that is between 7.8 and 9.4. Is this statement correct? Why or why not? (c) Consider the following statement: If the procedure of selecting a sample of size 50 and then computing the corresponding 95% interval is repeated 100 times, approximately 95 of the resulting intervals will include μ. Is this statement correct? Why or why not?
