A psychologist was interested in whether there was a gender difference in the use of email. She hypothesized that because women are generally better communicators than men, they would spend longer using email than their male counterparts. To test this hypothesis, the researcher sat by the email computers in her research methods laboratory and when someone started using email, she noted whether they were male or female and then timed how long they spent using email (in minutes). What should she report?
Welch Two Sample t-test
data: Time Using Email
t = -1.895, df = 7.177, p-value (two-tailed) = 0.099
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
-60.52295 6.52295
a. Females spent significantly longer using email than males, t(7.18) =
b. –1.90, p < .05.
c. Females spent significantly longer using email than males, t(14) =
d. –1.90, p < .05.
e. Females and males did not significantly differ in the time spent using email,
t(7.18) = –1.89, ns.
f. Females and males did not significantly differ in the time spent using email,
t(7.18) = –1.90, ns.
b. –1.90, p < .05.

Marianna Stankovic looked around her 4th grade classroom to see that everything was in order for the Halloween party. She carefully lit several candles that sat on a table near her desk. When the bell rang, her excited students rushed into the room and before Marianna could tell them to slow down, Marko bumped into the table and ignited his costume.
