The data collected from the experiment outlined in Question #6 are reported in the table below. These data are available either in the h4q9R.csv (if using R) or the h4q9RCmdr.csv (if using R commander) files on canvas.
animal | hba1c.before | hba1c.after |
1 | 5.45 | 4.75 |
2 | 5.37 | 3.61 |
3 | 4.98 | 3.78 |
4 | 5.06 | 4.39 |

Perform the appropriate test in R commander or R using the following functions:
setwd()
read.csv()
attach()
binom.test() *for a binomial test
fisher.test() *for a fisher exact test
t.test() *for a t-test
1. What is the resulting p-value? 2. Given the p-value obtained from the analysis conducted, what can we conclude from the results of the analysis? Choose the correct answer.
A. We reject the null hypothesis, the treatment did not affect the observed HbA1C levels
B. We reject the null hypothesis, the treatment significantly reduced the observed HbA1C levels
C. We fail to reject the null hypothesis, the treatment did not affect the observed HbA1C levels
D. We fail to reject the null hypothesis, the treatment significantly reduced the observed HbA1C levels
