INTRODUCTION

This is a document that I am typing for this class. It looks pretty cool. Let me make this bold and emphasize this line

New Information

I would to enter some data into this file

dat<-c(4,5,6,8,9,5,6,8,4)
mean(dat)
## [1] 6.111111
sd(dat)
## [1] 1.833333

The mean and standard deviation of this dataset is given above. I now want to plot the data.

boxplot(dat)

T-test

Now I want to do a T-test on the data

t.test(dat,mu=7)
## 
##  One Sample t-test
## 
## data:  dat
## t = -1.4545, df = 8, p-value = 0.1839
## alternative hypothesis: true mean is not equal to 7
## 95 percent confidence interval:
##  4.701886 7.520336
## sample estimates:
## mean of x 
##  6.111111
