 Researchers wanted to know if using a student's own name in a story would affect the child's attention span while reading. Four children read a story where the main character=s name was the same as theirs, whereas four other children read a story using ordinary names for the characters (like Tom, Dick, and Jane). The data below show the length of time the children spent reading the story. Using a .05 level of significance, can we conclude that including the child's name makes a difference in their attention span? (You may use an independent samples t-test or an ANOVA to answer this question.)

own name story: 13, 9, 7, 11

Ordinary story: 9,5,5,9
