1. Testing of two means is different for the situation when the populations are independent or they are related in the same way. (True or False)
2. Which is not a true statement about F- distribution

• F close to 1 might indicate that normal deviations are normal
• F can be equal to .5
• F equal to a significantly large number might mean that the standard deviations are not equal
• F-distribution curve depends on both df1 and df2

1. Critical value test and P-value test always lead to the same conclusion (True or False)
2. Polled sample is

• Used in all forms of testing of statements about 2 populations
• Used in two proportion testing
• Created by polling together the data from 3 or more samples
• A representative opinion of the local swimming pool members

1. Two variance testing requires the student-t distribution table (True or False)
2. Which of the following is NOT a possible alternative in two mean testing for independent populations?

• Standard deviations are irrelevant because the samples are very large
• Standard deviations are known
• Standard deviations are equal to each other
• Standard deviations are unknown

1. Two variance testing requires the student-t distribution (True or False)
