These tourists kayaked one day and rafted the next day. At the end of each day. they rated how much they liked the activity using a 10-point scale (1-strongly dislike to 10-strongly like).

Explanation / Answer

2) Since two different samples were created one for rafting and other for kayaking, but they were taken from the same people, we will say that the two samples are dependent.

So we will use two sample dependent t-test

3) The dependent variable here is importance of college education. Since it is measured in quantitative scale it is a quantitative variable.

The independent variable here is the attitude of seniors and fresmen and it is a qualitative variable, there is nothing quantitative about it.

The values of a qualitative variable do not imply a numerical ordering.
