Conduct a test at the a=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 pa > P2. The sample data are x = 120, n, 251, x2 = 132 and n, -311 (a) Choose the correct null and alternative hypotheses below O A. Ho P1 =Pz versus H, PP2 OB. Ho P, =...
(Round all intermediate calculations to at least 4 decimal places.) In order to conduct a hypothesis test for the population variance, you compute s2 = 68 from a sample of 12 observations drawn from a normally distributed population. Use the critical value approach to conduct the following tests at α = 0.05. Use Table 3. H0: σ2 ≤ 37; HA: σ2 > 37 a-1. Calculate the value of the test statistic. (Round your answer to 2 decimal places.)...
A sample of size n=35 was used to conduct a test of the null hypothesis H0: μ = 500. The value of the test statistic is 1.48. What is the p-value of the test statistic? Include 4 decimal places in your answer.
8. If you have data in the form of proportions and you want to conduct a hypothesis test, which of the following does not need to be known in order to compute a test statistic? A. The significance (or alpha) level. B. The sample proportion. C. The claimed population proportion. D. The sample size. E. All of the above need to be known in order to compute the test statistic. 9. It is claimed that 75% of parents believe their...
We are looking to calculate the power of a one-sided test from n independent observations from a N(μ, σ2) distribution with a null hypothesis of Ho : μ-μο and an alternative H1 : μ > μο. Supposing that we know σ2, we can form a test statistic o/Vn and reject the null hypothesis when T > 1.645. This test has level α = 0.05. We want a formula for the power of this test against the alternative that μ-A-This power...
