Change in Study Design or Results The Likelihood of Rejecting the Null Hypothesis A switch from using a one-tailed test to a two-tailed test      An increase in the population standard deviation (σ)      A decrease in the significance level (such as using α = .01 instead of α = .05)      A decrease in the sample size (n)        Suppose you fail to reject the null hypothesis. Then, the results of your study are
