Reference no: EM1318261

Q1) For y and x values listed, get simple linear regression equation, then analyze residuals by

a) Constructing histogram,

b) Using a normal probability plot,

c) Plotting residuals versus x values, and

d) Plotting residuals versus order in which they were observed. Do any of the suppositions of simple linear regression model appear to have been violated?

For regression line developed

year	x= US PRODUCTION OF MOTOR VECHILES	Y=TONS OF DOMESTIC STEEL
2000	12.83 MILLION	16.06 MILLION
2001	11.52	14.06
2002	12.33	14
2003	12.15	15.88
2004	12.02	13.86

a) Use 0.05 level in testing whether population coefficient of correlation could be zero.

b) Use 0.05 level in testing whether population regression equation could have slope of zero

c) Create 95% confidence interval for slope of population regression equation.
