Consider the following competing hypotheses: Ho: μ = 0, HA: μ ≠ 0. The value of the test statistic is z = -1.40. If we choose a 1% significance level, what is the correct decision and conclusion?
Multiple Choice Reject the null hypothesis; we can conclude that the population mean is significantly different from zero. 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. Do not reject the null hypothesis; we cannot conclude that the population mean is significantly different from zero.
