Suppose you want to test the claim that µ1 < µ2. Two samples are randomly selected from each population. The sample statistics are given below. At a level of significance of α = 0.05, when should you reject H0? n1 = 35 n2 = 42 x̅1 = 29.05 x̅2 = 31.6 s1 = 2.9 s2 = 2.8 Suppose you want to test the claim that u1<p2. Two samples are randomly selected from each population. The sample statistics are given...
A random sample of 40 binomial trials resulted in 16 successes. Test the claim that the population proportion of successes does not equal 0.50. Use a level of significance of 0.05. (a) Can a normal distribution be used for the p̂ distribution? Explain. Yes, np and nq are both less than 5.No, np is greater than 5, but nq is less than 5. No, nq is greater than 5, but np is less than 5.Yes, np and nq are both greater...
22) Suppose you want to test the claim that μ1 > μ2. Two samples are randomly selected from each population. The sample statistics are given below. At a level of significance of α = 0.10, find the test statistic and determine whether or not to reject H0. (8.1) n1 = 35 n2 = 42 x1 = 33 x2 = 31 s1 = 2.9 s2 = 2.8 A) z = 3.06; Reject H0 and support the claim that μ1 > μ2...
Suppose you want to test the following hypotheses: H0: p ≥ 0.4 vs. H1: p < 0.4. A random sample of 1000 observations was taken from the population. Answer the following questions and show your Excel calculation for each question clearly: (a) Let p ̂ be the sample proportion. What is the standard error of sample proportion (i.e., σ_p ̂ ) if H0 is true? (b) If the sample proportion obtained were 0.38 (i.e., p ̂=0.38), what is its p-value?...
