Ouestion Completion Status In which of the following situations the one-proportion z-test will NOT be applicabe? n 30, x 8, p0 = 0.25 n= 500, x = 300, po = 0.7 n= 80, x = 6, po 0.06 n= 240, x = 20, po0.08 QUESTION 20 According to a recent survey, 798 out of 1600 randomly selected adults in Abu Dhabi said that they use cell phones while driving. We are interested in testing the claim that the proportion of adults who use cell phones while driving exceeds 47%. Compute the test statistic. If needed, round your answer to two decimal places. QUESTION 21 A statistician is interested in testing whether more than 20% of teenagers are addicted to social media. If the test statistic was 2.3, what would be the p-value? QUESTION 22 AMTH 213 student claims that ZU students have on average 400 followers on Twitter. A random sample of 36 ZU students yielded an average of 410 with a standard deviation of 24. At 1% significance level, can we conclude that the student's claim is correct? (1) State the hypotheses, (2) check the assumptions of the test, (3) compute the test statistic (Round to one decimal place), (4) find the p-value (Round to three decimal places), and (5) state the conclusion.
