Melatonin Activity
Questions:
You will be asked below to evaluate the melatonin data from this study. Please
answer the following questions using the provided excel data sheet. Use full sentences, proper
grammar, and show your work where necessary.
1.
Develop a null hypothesis and appropriate alternative hypotheses for the conditions in
this study. You should have at least three alternative hypotheses. You may create a single
null hypothesis that describes all three comparison possibilities or list three separate ones.
(See the example data for ideas)
Null Hypothesis
There is no difference between the accumulation of melatonin in caffeine during the day and the
reduction of the circadian cycle impact of caffeine and wake-promotion in regular users.
2.
For the placebo control participants, calculate the average (mean) and the standard
deviation for the sample set by hand, using the formulas that you learned in class. Show
your work. Within you excel file, use the excel formulas to also calculate the averages
and the standard deviations for all three participant conditions. Do the average and
standard deviation values for the placebo trial that you calculated by hand match well
with the excel formula calculated data?
3.
In excel, make a new table of the different conditions, the melatonin averages, and the
standard deviations. Copy and paste your table here.
