A researcher wishes to determine if students who study for 30 minutes each day for one week will earn higher test scores than students who study for the same total amount of time (210 minutes) on the day before the test. To test this research statement, which of the following hypothesis tests should the researcher use?

      one-sample t-test
       two-sample t-test
       independent samples t-test
       dependent samples t-test
