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. Twenty-five minutes later the response was measured as the
concentration in the blood. What can the researchers conclude with
α = 0.01?
| Dose | |||
| Antidote | 5 | 10 | 15 |
| 1 | 0.6 1.1 1.1 |
2.1 1.5 6.2 |
3.1 4.1 5.9 |
| 2 | 1.1 1.2 1.1 |
1.7 1.3 1.5 |
2.1 3.1 2.1 |
Compute the corresponding effect size(s) and indicate
magnitude(s).
Antidote: η2
= ; ---Select--- na trivial effect small
effect medium effect large effect
Dose: η2
= ; ---Select--- na trivial effect small
effect medium effect large effect
Interaction: η2
= ; ---Select--- na trivial effect small
effect medium effect large effect
d) Make an interpretation based on the
results.
There is an antidote difference in blood concentration.There is no antidote difference in blood concentration.
There is a dose difference in blood concentration.There is no dose different in blood concentration.
There is an antidote by dose interaction in blood concentration.There is no antidote by dose interaction in blood concentration.

3. An experiment was conducted to evaluate the effectiveness of
a treatment for tapeworm in the stomachs of sheep. A random sample
of 24 worm-infected lambs of approximately the same age and health
was randomly divided into two groups. Twelve of the lambs were
injected with the drug and the remaining twelve were left
untreated. After 6 months, the lambs were slaughtered and the
following worm counts were recorded. Assume the counts are
approximately normally distributed.

An experiment is conducted to compare the effects of weathering
on paint of three different types. To do so, identical surfaces are
coated with some paint of each type that has been exposed to four
different environments. Measurements of the degree of deterioration
we made for each surface. The data set is uploaded to Moodle. What
can you say about the different paint types and different
environments and their effects on the paint degradation?

A researcher is running an experiment on the effectiveness of
three different energy drinks. She randomly selects 150 individuals
from the population and evenly splits them into three groups, each
which consumes a different energy drink.
1. The research/alternative hypothesis for this test is that at
least one of the three groups will be different. True or False?
The statistical results of the test are as follows: F(2, 147) =
2.24, p > .05.
2. In the above results, degrees...
