Question: 03
You have given the following information:
Estimated regression line: Y = 0.55 + 9.25X

Y = a + bx

a=0.55 , b=9.25
Standard error (S y.x)= 0.75
Degree of freedom (v) = 8
Level of significance (Alpha) = 5%
Tabulated value of t = 2.306
Calculate the confidence interval from this information

b+- t_(tabulated)* Sy.x

9.25 +- 2.306(0.75)

Now

9.25 – 2.306(0.75), 9.25 + 2.306 (0.75)

9.25 – 1.7295, 9.25 +1.7295

(7.5205, 10.9795)

Sorry i think i am late but wt can i do? lite waloon ko aqal nhi hai koi
