Part 3
For the following scenario: a) produce the best graph of the data you can using R and b) perform the best statistical analysis that you can in R to test the hypothesis. Include your null and alternate hypotheses, your test statistic, the degrees of freedom and P value, a conclusion with regards to your statistical hypotheses, and an overall (biological) conclusion.
Your friend is a clinical researcher studying the neurodegenerative disorder Parkinson’s
disease. Based on some preliminary research they hypothesized that regular coordinated
movement may help to slow the progression of the disease. To test this, they randomly
recruit 100 patient volunteers that have recently been diagnosed with Parkinson’s. Half of
the patients attend dance classes twice a week, while the other half attend social group
events twice a week that lack the dance component (control). After three months, patients’
progression was measured and recorded as either fast or slow based on expected average
rates. 38 and 21 patients in the dance and control groups, respectively, were rated slow.
After collecting the data your friend turns to you to complete the statistical analysis.
