Q:

I need help solving this ASAP.

 

Please DO NOT send answer in an excel docx without CLEARLY explaining the answer and how it was obtained. I am NOT going to understand where to find the answer on the doc on my own.

 

For the data set shown below, do the following,

a) compute the standard error, the point estimate for σ.

b) assuming the residuals = are normally distributed, determine sb1

c) assuming the residuals are normally distributed, test H:β1=0  versus   H1: β1≠ 0  at the a=0.05 level of significance.

 

X  20   30   40  50  60  

Y  100 97   89  83  72

Se= _____

 

do not round until the final answer, then round to the four decimal place as needed.
