Consider the following two statistical inference situations:
I. A technician at a water-bottling facility wishes to test whether one of the filling machines is delivering less fluid per bottle than it is intended to deliver.
II. Another technician at this same facility wished to determine the number of milliliters of water being delivered per bottle for the filling machine in question.
Which of these inference situations are
hypothesis testing problems?<--EndFragment-->
1.I only.
2.II only.
3.both I and II.
4.neither I nor II.
5.Situations such as I and II are not suitable for statistical inference.
Question 2The basic premise of hypothesis testing is to assume a status quo statement and examine sample information to assess the validity of the original statement. In order to no longer believe in the validity of the status quo statement, the sample statistic would need to be _____ to the population parameter.
1.unusual compared
2.similar in value
