JNU SSS 2021 Question 84: Hypothesis testing

Given testing for H0H_0H0​: μ1=μ2\mu_1 = \mu_2μ1​=μ2​, the values of the statistic ∣xˉ−yˉ∣(σ1n1+1n2)\dfrac{|\bar{x}-\bar{y}|}{\left(\sigma\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}\right)}(σn1​1​+n2​1​​)∣xˉ−yˉ​∣​ lies between 1.96 and 2.58 then what decision you make about H0H_0H0​

Plain-text version

Given testing for H₀: μ₁ = μ₂, the values of the statistic (|x̄-ȳ|)/((σ√(1/n₁+1/n₂))) lies between 1.96 and 2.58 then what decision you make about H₀ (A) Reject it at 5% level of significant (B) Reject at 1% level of significant (C) Accept it at 5% level of significant (D) Accept at 1% level of significant

Also written as: Given testing for H_0: mu_1 = mu_2, the values of the statistic (|x_bar-y_bar|)/((sigmasqrt(1/n_1+1/n_2))) lies between 1.96 and 2.58 then what decision you make about H_0
