Explanation / Answer

>n #sample size

#for fitness score for sheep with a body size of 10 kg

now, we want data from excel sheet so use following command

>data= read.table(file.choose(),header=TRUE) #choose data excel file and open

>data

> y=data[,1]

.> x=data[,2]

> v1=var(x)

>sig1=sqrt(v1)

> n=length(x)

>Lower.limit=(10-(qnorm(0.95)*(sig1/sqrt(n)))

>Upper.limit=(10+(qnorm(0.95)*(sig1/sqrt(n)))

#for fitness score for sheep with a body size of 12 kg

> v2=var(x)

>sig2=sqrt(v2)

>Lower.limit=(12-(qnorm(0.95)*(sig2/sqrt(n)))

>Upper.limit=(12+(qnorm(0.95)*(sig2/sqrt(n)))
