Introduction

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

New Information

I would like to enter some data into this file.

dat<-c(4,5,6,7,8,5,3,5,6,8,4)
mean(dat)
## [1] 5.545455
sd(dat)
## [1] 1.634848

The mean and standard deviation of this dataset is given above. I now want to generate a boxplot 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 = -2.9508, df = 10, p-value = 0.01451
## alternative hypothesis: true mean is not equal to 7
## 95 percent confidence interval:
##  4.447149 6.643760
## sample estimates:
## mean of x 
##  5.545455
