We have given the value obtained for the test statistic, z, in a one-mean z test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine the P-value in each case and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. a. Right tailed test: z= 2.03 b. Left tailed test: z= -1.84 c. Two-tailed test: z= 3.08 Please also give excel command needed to calculate each of the p-values for each of the questions
