A “social experiment” conducted by a TV program questioned what people do
when they see a very obviously bruised woman getting picked on by her
boyfriend. On two different occasions at the same restaurant, the same
couple was depicted. In one scenario, the woman was dressed
“provocatively,” and in the other scenario, the woman was dressed
“conservatively”. The table below shows how many restaurant diners were
present under each scenario, and whether or not they intervened.
Scenario
Provocative Conservative Total
Intervene Yes 5 15 20
No 15 10 25
Total 20 25 45

Some students do homework with the tv on. some researchers want
to see if people can work as effectively with as without

long it takes them to complete some relatively easy crossword
puzzles with and without tv on.

An experiment was conducted to see the effectiveness of two
antidotes to three different doses of a toxin. The antidote was
given to a different sample of participants five minutes after the
toxin. Thirty minutes later the response was measured as the
concentration in the blood. What can the researchers conclude with
an α of 0.01?

An experiment was conducted see the effect on fertilizer on
production of Mameys. H0 : fertilizers have no impact on mamey
production. H1 : fertilizers have an impact on mamey production.
There are four treatment (a=4); three types of fertilizer and the
control. Each treatment has four replicates (n=4). The number of
mameys produced is given in the table below.
A. Using these data complete a 1-Way ANOVA
table.
F1: 1, 2, 6, 11
F2: 2, 4, 2, 4
F3:...

tickets were sold; using the foot-in-the-door approach (getting
buyers to agree to buy one ticket first, then more), 3, 3, and 3
tickets were sold; and using no special technique, 1, 0, 1, and 2
tickets were sold. Using the .05 level, does sales technique...
