The following results are for two independent samples taken from the two populations. Sample 1 n₁ = 80 X₁ = 104 01 = 8.5 Sample 2 n₂ = x2 = 70 = 106 02 = 7.4 (a) What is the value of the test statistic? (Round your answer to two decimal places.) (b) What is the p-value? (Round your answer to four decimal places.)
Use the given information to find the P-value. Also, use a 0.05 significance level and state theconclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis).With H1: p (does not equal) 3/5, the test statistic is z = 0.78

You wish to test the following claim (Ha) at a significance level of a = 0.001. H.:µ1 = µ2 Ha:µ1 # µ2 You believe both populations are normally distributed, but you do not know the standard deviations for either. However, you also have no reason to believe the variances of the two populations are not equal (So use the "pool" option). You obtain the following two samples of data.

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
