Transcribed Image Text:
You want to determine whether the
amount of coffee that "coffee drinkers"
consume on a weekly basis differs
depending on whether the coffee drinker
also smokes cigarettes. You seek 20
volunteers from your college campus to
participate. Ten college students
reported that they consume coffee but
do not smoke cigarettes; these comprise
the Coffee-Only group, or Group 1.
Another ten college students reported
that they consumed coffee and also
smoked cigarettes; these comprise the
Coffee + Cigarettes group, or Group 2.
Then you ask them to monitor the
frequency of 8 ounce cups of coffee they
consumed over a seven day period.
Which of the following are the correct
statements of the null and alternate
hypotheses, Ho and HA?
O Ho: H1 H2 and HA: μ1:
με
≤
Ho: H1 H2 and HA: μ1 > μ2
M2
με
O Ho: H1 H2
<
and HA: H1 ≥ 2
O Ho: H1 H2
and HA: H1 <μ2
Ho: H1
=
H2 and Hд: 1 # M2
Ho: H1 H2 and HA: μ1 =
= H2
