Question

How do I set up the code for #5? I have 1-4 computed fine. Would it be

> Sum(height) / length (length) ?

Define the following vectors, which represent the weight and height of people on a

particular team (in inches and pounds):

height <- c(59,60,61,58,67,72,70)

weight <- c(150,140,180,220,160,140,130)

Define a variable:

a <- 150

Step 1: Calculating means

1) Compute, using R, the average height (called mean in R

2) Compute, using R, the average weight (called mean in R)

3) Calculate the length of the vector ‘height’ and ‘weight’

4) Calculate the sum of the heights

5) Compute the average of both height and weight, by dividing the sum (of the height

or the width, as appropriate), by the length of the vector. How does this compare to

the ‘mean’ function?

Explanation / Answer

public class p1 {

public static void main(String[] args)

{

int[] height={59,60,61,58,67,72,70};

int[] width={150,140,180,220,160,140,130};

int a=150;

int len_height,len_width,i,j;

double [] R=new double[2];

//3.CALCULATING LENGTH OF VECTOR HEIGHT AND WIDTH

len_height=height.length;

len_width=width.length;

//1.CALCULATING AVERAGE HEIGHT

int avg=0;

for(i=0;i<len_height;i++)

{

avg=avg+height[i];

}

R[0]=avg/len_height;

System.out.println("AVERAGE HEIGHT="+R[0]);

//2.CALCULATING AVERAGE WIDTH

avg=0;

for(i=0;i<len_width;i++)

{

avg=avg+width[i];

}

R[1]=avg/len_width;

System.out.println("AVERAGE WIDTH="+R[1]);

//4.SUM OF HEIGHT

int sum=0;

for(i=0;i<len_height;i++)

{

sum=sum+height[i];

}

System.out.println("SUM OF LENGTH="+sum);

//5. AVERAGE OF BOTH HEIGHT AND WIDTH

double final_avg=0;

//TOTAL AVERAGE=(AVERAGE OF HEIGHT+AVERAGE OF WIDTH)/2

final_avg=(R[0]+R[1])/2;

System.out.println("AVERAGE OF BOTH OF HEIGHT AND WIDTH="+final_avg);

}

}
