2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

A researcher conducts a two-sample t-test in order to test the following hypotheses: H0 :µa = µB vs. H1: µA > µB. She finds that the p-value is .075. Her colleague wishes to conduct the same hypothesis test, but will change his alternative hypothesis to µA=/=µB and will use α = .10. What can be said about the results of his test? (a) He will fail to reject the null hypothesis. (b) He will reject the null hypothesis. (c) Whether he rejects the null hypothesis depends on the brand of statistical software he uses. (d) There is not enough information provided to determine the results of his test.
A janitor at a large office building believes that his supply of light bulbs has too many defective bulbs. The janitor's null hypothesis is that the supply of light bulbs has a defect rate of p=0.07 (the light bulb manufacturer's stated defect rate). Suppose he does a hypothesis test with a significance level of 0.05. Symbolically, the null and alternative hypothesis are as follows H0: p=0.07 and Ha: p>0.07. The janitor calculates a p-value for the hypothesis test of approximately 0.087. Choose the correct interpretation for the p-value. A. The p-value tells us that if the defect rate is 0.07, then the probability that the janitor will have 27 defective light bulbs out of 300 is approximately 0.087. At a significance level of 0.05, this would not be an unusual outcome. B. The p-value tells us that the true population rate of defective light bulbs is approximately 0.087. C. The p-value tells us that the probability of concluding that the…
Would you favor spending more federal tax money on the arts? Of a random sample of n1 = 86 politically conservative voters, r1 = 18 responded yes. Another random sample of n2 = 85 politically moderate voters showed that r2 = 21 responded yes. Does this information indicate that the population proportion of conservative voters inclined to spend more federal tax money on funding the arts is less than the proportion of moderate voters so inclined? Use α = 0.05. (a) State the null and alternate hypotheses. H0: p1 = p2; H1: p1 > p2 H0: p1 = p2; H1: p1 < p2 H0: p1 = p2; H1: p1 ≠ p2 H0: p1 < p2; H1: p1 = p2 (b) What sampling distribution will you use? What assumptions are you making? The Student's t.

In a given hypothesis test, the null hypothesis cannot be rejected at the 0.005 and the 0.01 level of significance, but can be rejected at the 0.03 level. The most accurate statement about the p−value for this test is: A. p-value<0.005B. 0.005<p-value<0.03C. 0.01<p-value<0.03D. p-value>0.03E. p-value=0.01F. 0.005<p-value<0.01
(b)Based on your answer to part (a), which statement below is true? Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. Since the p-value is greater than the level of significance, the null hypothesis is rejected. Since the p-value is greater than the level of significance, the null hypothesis is not rejected.
