5) The table below represents data on a variable of interest collected from two independent groups, in which each group was randomly assigned ten participants. A researcher is interested in testing whether the two groups have different means.
Group 1 4 4 2 6 3 5 6 1 5 4
Group 2 6 10 4 7 8 5 9 10 6 7
a) What are the appropriate hypotheses for this analysis? b)
What is/are the critical value(s) for this test at a 0.05 alpha
level? c) What is the estimated standard error for this test? d)
What is the observed value of the appropriate test statistic? e)
What is your decision regarding the stated hypotheses?

The table below represents data on a variable of
interest collected from a single sample. It is known that the
variable of interest has a mean of 25 in the general population. A
researcher is interested in testing whether the population from
which this sample was selected scores higher than the general
population.

Correctional services were interested in evaluating a
cognitive-behavioural based intervention designed to reduce
violence and offending. A group of researchers assigned nine
offenders on parole into a control group for one year and recorded
the number of violent incidents perpetrated by the offenders. Then,
these offenders were given the intervention for one year and the
number of violent incidents perpetrated by the offenders was
recorded following the treatment. The researchers are interested in
testing whether the treatment had any effect...

1. A researcher is comparing scores from two treatment groups
using independent samples t test. Use a Hartley’s
F-max test to examine this assumption (each group has 6
participants, s2 in group 1 is 20, and s2 in
group 2 is 15, set alpha level at .05). Also, how should this
researcher estimate the standard error in the independent samples

information from a group of 64 patients, and calculates a sample
mean of 6.4 hours of sleep and a standard deviation of
s=0.8.

A researcher was interested in learning about the effect of
caffeine consumption on problem solving. To examine this
relationship, participants were randomly selected and assigned to
one of four conditions: no caffeine consumption, 100 mg dosage of
caffeine, 200 mg dosage of caffeine, or 300 mg dosage of caffeine.
The participants were then asked to solve as many anagrams* as
possible in a 5 minute period. The results of the study are
presented below.
*Anagrams are word puzzles that are...
