3 = 2/3 m
m = 9/2
by the matrix property of associative: (A+B)+C = A+(B+C)
H = [-2 8 -1]
m x H = 9/2 x [-2 8 1] = [-9 36 -9/2]

If p-value ≥ , we are fail to reject the null hypothesis .
As per given , we have
The p value for an independent samples t-test is 0.043.
The level of significance is
Since , 0.043 < 0.05.
i.e. p-value <
It means we reject the null hypothesis .
It means the null hypothesis is false.
Hence , the correct decision in this scenario is to favor the null hypothesis : False
