Coefficients Standard Error t Statistic p-value Intercept 1.7 0.384212 4.424638 0.00166 x1(website visitors) 0.04 0.014029 2.851146 0.019054 x2(download format) -1.5666667 0.20518 -7.63558 3.21E-05

Explanation / Answer

here regression equation is y=(b0+b1x1+b2x2)*1000000

where b0=-1.7 ; b1 =0.04 ; b2 =-1.566667 ; x1 =10 ; x2=1

hence y=(1.7+0.04*10-1.566667)*1000000=533333
