For or this problem, collect data on any variables of interest
(sample size
for each group of
the two groups n=>30)
and perform a
two-sided
significance test for
comparing two
independent population means.
You can also simulate your own data.
Address the following:
a.
A brief introductory paragraph describing the problem.
b.
Set up your framework in a null and alternative hypothesis using symbols and
notation as they are presented in the textbook.
c.
A paragraph describing how you collected the data (i.e., the number of observations,
time of day, etc.
Please present the raw data in a table.
d.
Create a graph of the
means
of the two samples
using Excel
. Clearly label your axes,
and give your figure a title.
e.
A section explaining the results of the analysis (calculated statistics, and p-values).
Based on what you find, state your decision (whether you reject or fail to reject the
H0
) and conclusion (whether you have sufficient or insufficient evidence for
H1
f.
Describe how would you change the experimental design to become
dependent or related
