A sociologist is interested in the relation between x= number of job changes and y= annual salary fo


Question: x- represents the number of fouls more than the opposing team
y- represents the percentage of times the team with the larger number of fouls wins the game.

X- 0 2 5 6
Y- 50 45 33 26
a- draw a scatter diagram displaying data
b-verify the given sums x=13,y=154, x2=65, y2=6290, xy=411 and r = -0.988.
c-find x , y ( the line is suppose to be over the x and but i could not get it on my comp.), a and b. The find the equation of the least squares line y=a + bx.
d- graph the least squares line on your scatter diagram. be sure to use the point ( x,y ) as one of the points on the line.
e- find the value of the coefficient of determination r2. what percentage of the variation i y can be explained by the corresponding variation in x and the least squares line? what percentage is unexplained.
