Consider the following competing hypotheses: Ho U=0, HA *0. The value of the test statistic is z=-1.50. If we choose a 5% significance level, what is the correct decision and conclusion? Multiple Choice Do not reject the null hypothesis; we cannot conclude that the population mean is significantly different from zero. Do not reject the null hypothesis; we can conclude that the population mean is significantly different from zero. Reject the null hypothesis, we can conclude that the population mean is significantly different from zero. A 99% confidence interval for the population mean yields the following results: [-3.79, 5.86]. At the 1% significance level, what decision should be made regarding the following hypothesis test with Ho = OHAU #0? Multiple Choice Do not reject Ho: we cannot conclude that the mean differs from zero. Reject Ho: we cannot conclude that the mean differs from zero. Reject Ho we can conclude that the mean differs from zero. Consider the following competing hypotheses: Ho U=0, HA *0. The value of the test statistic is z=-1.50.
