We can find the two proportions as we are given with the success chances. After that, we can find the test statistic. 95% confidence interval can be found by using the formula.
Therefore, a 95% confidence interval is between -0.44292 and -0.08375.

Two different simple random samples are drawn from two different populations. The first sample consists of 40 people with 21 having a common attribute. The second sample consists of 2000 people with 1429 of them having the same common attribute. Compare the results from a hypothesis test of p 1=p2 (with a 0.05 significance level) and a 95% confidence interval estimate of p 1-p2. What are the null and alternative hypotheses for the hypothesis test? What is the test statistic?...

Independent random samples of size n1=38 and n2=86 observations, were selected from two populations. The samples from populations 1 and 2 produced x1=18 and x2=13 successes, respectively. Define p1 and p2 to be the proportion of successes in populations 1 and 2, respectively. We would like to test the following hypotheses: H0:p1=p2 versus H1:p1≠p2 (a)To test H0 versus H1, which inference procedure should you use? A. Two-sample z procedure B. One-sample z procedure C. One-sample t procedure D. Two-sample t...

Suppose that based on two independent samples, the 95% confidence interval for the difference between two population proportions, p1−p2 is (-0.29, -0.01). If a test of hypotheses H0: p1−p2 = 0 versus Ha: p1−p2 ≠ 0 was conducted at 0.05 level of significance based on these samples, the decision would be to .. retain the null hypothesis? reject the null hypothesis?

Independent random samples, each containing 90 observations, were selected from two populations. The samples from populations 1 and 2 produced 50 and 42 successes, respectively. Test H0:(p1−p2)=0 against Ha:(p1−p2)≠0. Use α=0.04. (a) The test statistic is (b) The P-value is (c) The final conclusion is A. We can reject the null hypothesis that (p1−p2)=0 and accept that (p1−p2)≠0. B. There is not sufficient evidence to reject the null hypothesis that (p1−p2)=0. side note- no idea how to find a test...
