In simple linear regression, most often we perform a two-tail test of the population slope b ₁ to determine whether there is sufficient evidence to infer that a linear relationship exists. The null hypothesis is stated as: A)H ₀: b ₁ = 0 B)H ₀: b ₁ = b ₁ C)H ₀: b ₁ ¹ 0 D)None of these choices.

The null hypothesis in simple linear regression testing for the slope ($b_1$) typically states that there is no linear relationship between the independent and dependent variables, which is mathematically represented as $H_0: b_1 = 0$. This implies that any observed relationship is due to random chance.
