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...
For one binomial experiment, n1 = 75 binomial trials produced r1 = 60 successes. For a second independent binomial experiment, n2 = 100 binomial trials produced r2 = 85 successes. At the 5% level of significance, test the claim that the probabilities of success for the two binomial experiments differ. (a) Compute the pooled probability of success for the two experiments. (Round your answer to three decimal places.) (b) Check Requirements: What distribution does the sample test statistic follow? Explain....
You wish to test the following claim ( H a ) at a significance level of α = 0.05 . H o : p 1 = p 2 H a : p 1 ≠ p 2 You obtain 63.1% successes in a sample of size n 1 = 203 from the first population. You obtain 80.9% successes in a sample of size n 2 = 230 from the second population. For this test, you should NOT use the continuity correction,...
You wish to test the following claim (H) at a significance level of a - 0.005. Ha:PI P2 You obtain 41.8% successes in a sample of size n2 536 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribrn sarmple of size ni = 694 from the first population. You obtain 31% successes in a What is the test statistic for this...

You wish to test the following claim (HaHa) at a significance level of α=0.005. Ho:p1=p2 Ha:p1>p2 You obtain 106 successes in a sample of size n1=522 from the first population. You obtain 33 successes in a sample of size n2=270 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. What is the test statistic for this sample?

i will rate and comment your answer thank you You wish to test the following claim (H) at a significance level of a = 0.05. HP = P2 HP: <P2 You obtain 90 successes in a sample of size na = 787 from the first population. You obtain 75 successes in a sample of size 12 = 583 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as...
A random sample of n = 1,000 observations from a binomial population contained 337 successes. You wish to show that p < 0.35. Given: H0: p = 0.35 versus Ha: p < 0.35 Solve: Calculate the appropriate test statistic. (Round your answer to two decimal places.) z =?? Provide an α = 0.05 rejection region. (Round your answer to two decimal places. If the test is one-tailed, enter NONE for the unused region.) z> ?? z<??
PLEASE SHOW CALCULATOR WAY You wish to test the following claim (Ha) at a significance level of α 0.02. Ho:p1 = p2 You obtain 142 successes in a sample of size ni = 725 from the first population. You obtain 48 successes in a sample of size n2 = 289 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. What is...
