A psychologist was interested in whether there was a gender difference in the use of e-mail. She hypothesized that because women are generally better communicators than men, they would spend longer using e-mail than their male counterparts. To test this hypothesis, the researcher sat by the e-mail computers in her research methods laboratory and when someone started using e-mail, she noted whether they were male or female and then timed how long they spent using e-mail (in minutes).
Based on the SPSS output below, what should she report?

a.
Females spent significantly more time using e-mail than males, t(7.18) = -1.90, p < .05.
b.
Females spent significantly more time using e-mail than males, t(14) = -1.90, p < .05.
c.
Females and males did not differ significantly in the time spent using e-mail, t(7.18) = -1.90, ns.
d.
Females and males did not differ significantly in the time spent using e-mail, t(14) = -1.90, ns.
