The alternate hypothesis is not rejected when the variables have an associated relationship. WebIn a statistical test, rejecting or failing to reject a claim depends on “how strong is the sample evidence”. To determine the strength of the sample evidence, we need to know the sampling distribution of the corresponding sample statistic. Central limit theorem from chapter 6 (section 6.3 & 6.4) gives us sampling
