1. Given H0​:μ=​25, Ha​:μ≠​25, and P=0.031. Do you reject or fail to reject H0 at the 0.01 level of​ significance?

2. Suppose you want to test the claim that μ1≠μ2. Two samples are randomly selected from each population. The sample statistics are given below. At a level of significance of α=​0.02, when should you reject H0​?  n1=​51, n2=​38, x1=2​, x2=2.4​, σ1=​0.76, σ2=0.51

i need help with both questions please
