K Conduct a test at the α = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether p₁> P2. The sample data are x₁ = 116, n₁ = 244, x2 = 132, and n₂ = 313. (a) Choose the correct null and alternative hypotheses below. OA. Ho P1 P2 versus H₁: P1 P2 OB. Ho P₁ P2 versus H₁: P₁ P2 OD. Ho p₁ =0 versus H₁:.p₁ #0 (b) Determine the test statistic. Zo= (Round to two decimal places as needed.) (c) Determine the P-value. The P-value is (Round to three decimal places as needed.) What is the result of this hypothesis test? OA. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p₁ #p2- OB. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p₁ P2- OD. Reject the null hypothesis because there is sufficient evidence to conclude that p₁…

True/false Questions: Decide whether the following statements are true or false. (3p) a. A normal distribution will usually have outliers. b. A z-score represents the number of standard deviations above or below the mean. c. The mean of the sampling distribution of the means is equal to the mean of the population from which the values were sampled.
What is the test statistics and critical values. I got 4.20 for the test statistic, but it says its incorrect.
Each of the following statements contains an error. Describe the error and then correct the statement. (9p) a. For a symmetric distribution, the mean will be smaller than the median. b. When taking SRSs from a large population, larger sample sizes will result in larger standard deviations of x. c. The central limit theorem states that for large n, the shape of the sampling distribution is approximately the shape of the population distribution.
(2 points) Suppose that we are to conduct the following hypothesis test: Ho p H₁ == 1050 1050 στ == Suppose that you also know that σ = 250, n = 95, 1090, and take a = 0.1. Draw the sampling distribution, and use it to determine each of the following: A. The value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form (-00, a) is expressed (-infty, a), an answer of the form (b, x) is expressed (b, infty), and an answer of the form (-00, a) U (b, c) is expressed (-infty, a)U(b, infty). B.
