13. Find the p-value using the give information below (a) A two-sided test with the value of the test statistics $z^* = 1.78$. (b) A left-sided test with the value of the test statistics $z^* = -2.28$ (c) A right-sided test with the value of the test statistics $t^* = 2.13$ and $n = 20$. (d) A left-sided test with the value of the test statistics $t^* = -2.73$ and $n = 25$.

Consider the hypotheses shown below. Given that x = 43, σ = 13, n = 36, α = 0.01, H0: μ ≤ 40 H1: μ > 40 a. Z-test statistic b. Critical z-score c. Because the test statistic ___ ___ the null hypothesis d. P-value Consider the hypotheses shown below. Given that x = 113, σ = 26, n = 41, α = 0.05, H0: μ = 119 H1: μ ≠ 119 a. Z-test statistic b. Critical z-score c. Because the test statistic ___ ___ the null hypothesis d. P-value

34) Use the one-proportion z-test to perform the specified hypothesis test. x = 30, n = 169, Ho: p = 0.11, H1: p ≠ 0.11, α = 0.05 A) z = 2.81, Critical values = ±1.96, Reject H0. B) z = 2.81, Critical values = ±1.645, Reject H0. C) z = 1.36, Critical values = ±1.96, Reject H0. D) z = 1.36, Critical values = ±1.645, Reject H0. E) None of the above; Do Not Reject H0.
