What is the regression test of B (beta)? and what are the steps in completing this test?
regression test of beta it to test whether beta is significant or not
..............
steps::
slope hypothesis test
tail= 2
Ho: ß1= 0
H1: ß1╪ 0
n= 8
alpha = 0.05
estimated std error of slope =Se(ß1) = Se/√Sxx
t stat = estimated slope/std error =ß1 /Se(ß1)
t-critical value [excel function: =T.INV.2T(α,df)
]
Degree of freedom ,df = n-2
compare test stat with critical value
if test stat > critical, reject Ho
regression is significant
if test stat < critical , do not reject Ho
regresssion is insignificant
