$$?x=15;?y=86.9;?x^2=55;?y^2=1544.73;?xy=273.4$$ Sociology: Job Changes A sociologist is interested in the relation between $$x=$$ number of job changes and $$y=$$ annual salary (in thousands of dollars) for people living in the Nashville area. A random sample of 10 people employed in Nashville provided the following information: Lomplete pa:s (a) through (c), given $$?x=60;?y=359;?x^2=442;?y^2=13,013;?xy=2231$$. (d) If someone had $$x=2$$ job changes, what does the least-squares line predict for $$y$$, the annual salary? (b) input following values here: $$\stackrel{?}{x}=$$ in least-squares line equation $$y=a+bx$$, slope $$b$$ : $$y$$-intercept $$a=$$ (c). $$r=$$ what percentage= show all your (d) pre: a far $$y$$, the annual salary is show your works on your paper, take picture and upload. math $$12\mathrm{zp}186\mathrm{pdf}$$
