#Reflection Questions: How was the install process? Anything I should know for future students? Not everyone has coding experience, so maybe going into more depth about what things actually mean would make it easier (i.e. knit, package, etc.) Have you used any statistical software before? I have used excel and python but I don’t know if python is considered a stat software.

Run the histogram and mean

hist(epi.bfi$bdi)

mean(epi.bfi$bdi)
## [1] 6.779221

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
