among 60 frogs randomly sampled from group one, 40 are green. among 50 frogs randomly sampled from group two, 37 are green. let P1 and P2 be the proportions of green frogs in groups one and two respectfully.

i) compute the observed value of the test statistic and the p-value for testing H0: P2 - P1 = 0.05 vs H1: P2 - P1 > 0.05

ii) prior to the previous study, determine the common sample size n needed to estimate P2-P1 to within 0.04 with 92% confidence.

    A survey found that 40​% of 822 randomly sampled teens said that their parents checked to see what Web sites they visited. The following year the same question posed to 809 teens found 42​% reporting such checks. Do these results provide evidence that more parents are​ checking? Let p1 and p2 be the proportions of parents checking the Web sites visited in the first and second years respectively. Choose the correct null and alternative hypotheses below.

    A new disease has annihilating amphibian populations at unprecedented levels. Researchers has been trying to develop some treatment that can counteract the disease and save some of the amphibian populations. To test which of two potential solutions is more effective, they take a sample of frogs and randomly divide them into two groups. After being treated, 256 of the 400 frogs in group 1 ended up surviving exposure to the pathogen; 300 of the 482 frogs in the second group...

    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....
