Expert Solution

Here we are given with details

n = 10

we know that best fit line is given by :

where

and

So from above equations

and

So the best fitted line is

The following program is supposed to read 10 pairs of 2D coordinates, (xi , yi ), and print the average coordinate. However, it does not work correctly. Fix the program so that it compiles with no errors or warnings and correctly computes the average coordinate. int main() { float coords[9][2] = { 0 }; float sum[2]; while (i < 2) { scanf("%d%d", &coords[i][0], coords[i][1]); sum[0] += coords[i][0]; sum[1] += coords[i][1]; } printf("Average coordinate: (%.2d, %.2d)\n", sum[0], sum[1]); return 0; }...

Assume n independent observations, denoted Xi, (i=1,....n), are taken from a distribution with a mean of E(X)=μ and variance V(X) =σ2. Prove that the mean of the n observations has an expected value of E(X)=μ and a variance of V(X) =σ2/n. Use the appropriate E and V rules in your answer. What happens as n becomes large? What does this tell you about the quality of the sample mean as an estimate of μ as the sample size increases?
