Question

suppose we are given the following information:

sample size (n) = 100

standard error of the slope of the regression line (SE_b1) = 2

y=100 + 4x

(multiple choice question)

what is the P - value for a test of the null hypothesis that the slope is zero versus the alternative hypothesis that the slope is not zero?

a.) < 0.01

b.) < 0.05

c.) < 0.02

d.) none of the above

Answer 1

n=   100              

estimated std error of slope =   2.0000
                  
t stat = estimated slope/std error =ß1 /Se(ß1) =    4.0000   /   2.0000   =   2.0000
                     
p-value =    0.0483              

b.) < 0.05

Thanks in advance!
