Pick a sample where the confidence interval at C = 80% does not contain the true mean, but the confidence interval at C = 95% does contain the true mean. Test the hypothesis that the true mean is 0 versus a two-sided alternative twice: once at a significance level of 0.20 and again at a significance level of 0.05.
The sample I'm using is .328778
