We are given regression equation :
=
25.5 + 1.35*x
So b0 = 25.5 and b1 = 1.35
n = 25
SSE = SST - SSR = 1430 - 1188.55
SSE = 241.45
H0 : β1 = 0 vs Ha : β1 ≠0
Test statistic :
t =
=
t = 1.35 / 0.3208
t = 4.21
Critical value : α = 0.05 and df = n -2 = 23
For two tail area 0.05 and df = 23 , critical value is 2.069 --- ( from t distribution table )
As | t | is greater than 2.069 , We reject the null hypothesis
Answer : reject H0
