Attitude(X) 0.729506623 0.150818051 4.836998084 0.001293059 0.381719574 1.077293672 0.381719574 1.077293672

Regression equation:

Performance(Y) = 8.5665+0.7295* Attitude(X)

Correlation coefficient (r) = 0.8632

Hypothesis:

H0​:ρ=0

HA​:ρ̸​=0

df = n−2 = 10−2 = 8

Let α = 0.05

rc ​= 0.632 (Use r table)

r stat > rc, Reject H0

Therefore, there is a signioficant linear relationship between X and Y variables

There is sufficient evidence to conclude that there is significant relation between employees job performance and attitude
