I need help with figuring out which of my variables is best suited to be tested as a t-test of independent means and which is best for a t test of dependent means.

Here are the following scenarios and data I need to use:

First scenario:Conduct a t test to investigate if there is a difference between men and women in their life satisfaction scores.

There are 10 males and 10 females with the following scores of general life satisfaction

8 3 7 4 10 5 3 7 9 2 6 5 8 3 10 7 4 10 5 1

Second scenario:

Imagine that your participants have all taken part in a program designed to increase their active minutes per week. Create a new variable 'number of minutes exercised weekly post intervention' and enter data for this variable. Conduct a t test to investigate if there is a difference between the number of minutes exercised per week and the number of minutes exercised per week post intervention.

#of minutes exercised weekly

100 140 30 0 200 180 160 60 0 230 300 120 45 60 310 0 45 150 190 0 # of minutes of exercise weekly post intervention

200 210 130 60 260 250 220 115 100 310 380 240 160 140 400 130 100 270 330 150
