The Pew Research Center reported in 2018 that 68% of U.S. adults rated "reducing health care costs" as a national priority. This year a survey is conducted with a national sample of 1,505 U.S. adults selected by a combination of landline and cell phone random digit dials. This year's survey finds that 70% of the sample says that "reducing health care costs" is a national priority. We test the following hypotheses: LaTeX: H_0 H 0 : The proportion of U.S....

A polling agency reports that over 16% of U.S. adults are without health care coverage. In a random survey of 1420 U.S. adults, 256 said they did not have health care coverage. At α = 2%, is there enough evidence to support the agency’s claim? State the null and alternative hypotheses and identify which represents the claim. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning and sketch the graph of the problem. Find the p-value...

331 of 586 randomly selected U.S. adults interviewed said they would not be bothered if the National Security Agency collected records of personal telephone calls they had made. Is there sufficient evidence to conclude that a majority of U.S. adults feel this way? Test the appropriate hypotheses using a 0.01 significance level. (Round your test statistic to two decimal places and your P-value to four decimal places.) z = P = The data (provides enough OR does not provide enough)...

Marketers believe that 83.46% of adults in the U.S. own a cell phone. A cell phone manufacturer believes the proportion is different than 0.8346. 37 adults living in the U.S. are surveyed, of which, 23 report that they have a cell phone. Using a 0.01 level of significance test the claim. The correct hypotheses would be: H0:p≤0.8346H0:p≤0.8346 HA:p>0.8346HA:p>0.8346 (claim) H0:p≥0.8346H0:p≥0.8346 HA:p<0.8346HA:p<0.8346 (claim) H0:p=0.8346H0:p=0.8346 HA:p≠0.8346HA:p≠0.8346 (claim) Since the level of significance is 0.01 the critical value is 2.576 and -2.576 The...

16) A national tabloid newspaper reported that 30% of adults in the general population believe that life exists elsewhere in the universe. A TV news station surveyed a random sample of adults from the general population and reported that 36 out of 100 sampled hold this belief. A right-tail hypothesis test is performed. What is the conclusion at a level of significance of 10%? 5%? 1%? (A) P -value = .0952, and so the 30% claim should be disputed at...
