Homework 10 / Task 1
Read the options to question 1 carefully and choose the correct choice.
1. Which of the following is false? (4 points)
a. We use two sided t-test when we are checking if the averages of the two variables
are different, with no prior assertion on which is larger of the two.
b. We use one sided t-test when we are checking if the averages of the two variables
are different, but now we are more specific. We want to show that X has a significantly
larger/smaller average than Y.
c. We need to perform the averages of the two variables data set when one sided t-test
is chosen in order to see if the averages are consistent with the claim.
d. The one sided t-test and two sided t-test performed on the same data sets should
return the same
-value excel returns on a one sided t-test is incorrect and meaningless if the
averages computed on the data sets are inconsistent with the claim.
