Which test should be used one samples t test, independent samples t test or dependent samples t test and how to set up the hypothesis
An educational psychologist was interested in whether using a student’s own name in a story affected children’s attention span while reading. Six children were randomly assigned to read a story under ordinary conditions (using names like Dick and Jane). Five other children read versions of the same story, but with each child’s own name substituted for one of the children in the story. The researcher kept a careful measure of how long it took each child to read the story. Results are shown below with longer times indicative of shorter attention spans. Using a twotailed test, determine whether including the child’s name made a difference in attention span.

You can see that you have two samples here so you will do either an indep or dep. test.
We usually use a dependent test if we are using twins or triples, married couples or if we repeat the test with the same students and using a different criteria. That did not happen here.

It depends on your book
It can be set up as
Ho: mu1 = mu 2
Ha: mu1 does not equal mu2
or other books write it as:
Ho: mu1  mu2 = 0
Ha: mu1  mu2 does not = 0
