A medical researcher claims that 5% of children have asthma.In a random sample of 100 children 7.2% say they have asthma. At α=.05, evaluate the claim by: Identifying the claim and H0 and Ha, Finding the appropriate standardized test statistic, Finding the P-value or the rejection region, Deciding whether to reject or fail to reject the null hypothesis, and Interpreting the decision in the context of the original claim.
Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2164passenger cars in a particular region, 251 had only rear license plates. Amon355commercial trucks, 50 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.05 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval.
In a survey taken in 2020, 20 out of 50 women and 17 out of 45 men said that they felt our country was headed in the wrong direction regarding universal health care. Do these data provide sufficient evidence at the 0.01 level of significance to conclude that the proportions of women and men that feel out country is headed in the wrong direction regarding healthcare are equal? Use the P-Value Method of Testing. In your work space below, you will need to have -1. The null hypothesis, Ho 2. The alternative hypothesis, H1 3. The test statistic 4. The type of test(left, right, two-tailed) and the p-value 5. The decision to accept Ho or reject Ho
A simple random sample of front seat occupants involved in car crashes is obtained. Among 3281 occupants not wearing seat belts, 40 were killed. Among 9285 occupants wearing seat belts, 125 were killed. Does the data provide evidence to conclude that seat belts are effective in avoiding fatalities? Perform a hypothesis test at the 1% significarnce level. a) Define the parameters and state null and alternative hypothesis b) Find Test Statistics c) Find the p-value d) Conclusion
Test a claim , identify the null hypothesis, alternative hypothesis, test statistic, p-value, and then stat the conclusion about the null hypothsesis. As well as the final conclusion that addresses the original claim. Among 2161 passenger cars, in a particular region, 251 only had rear license plates. Among 382 commercial trucks, 54 had rear licens plates. A reasonable hypothesis is that the commercial truck owenrs violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.05 signifigance level to test that hypothesis. A. Test the claim using the hypothesis test B. Test the claim by constructing an appropriate confidence interval What is the test statistic?
A movie based on a best-selling novel was recently released. Six hundred viewers of the movie, 235 of whom had previously read the novel, were asked to rate the quality of the movie. The survey showed that 141 of the novel readers gave the movie a rating of excellent, while 248 of the non-readers gave the movie an excellent rating. b. Can we conclude, on the basis of a hypothesis test about p1 – p2, that the proportion of the non-readers of the novel who thought the movie was excellent is greater than the proportion of readers of the novel who thought the movie was excellent? Use a 0.05 level of significance. (Hint: This is a one-tailed test.) Choices: H0: pNR – pR ≤ 0; z = 2.274 > 1.645; p-value = 0.0815 < .05; reject H0 H0: pNR – pR ≤ 0; z = 2.274 > 1.645; p-value = 0.0115 < .05; accept H0 H0: pNR – pR ≤ 0; z = 2.274 > 1.645; p-value = 0.0115 < .05; reject H0 H0: pNR – pR ≤ 0; z = 3.274 > 1.645; p-value = 0.0115 < .05; reject H0
A researcher took a random sample of 200 new mothers in the United States (Group 1) and found that 16% of them experienced some form of postpartum depression. Another random sample of 200 new mothers in France (Group 2), where mothers receive 16 weeks of paid maternity leave, found that 11% experienced some form of postpartum depression. Can it be concluded that the percent of women in the United States experience more postpartum depression than the percent of women in France? Use α=0.05. Select the correct alternative hypothesis and decision

1. Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2051 passenger cars in a particular region, 227 had only rear license plates. Among 387 commercial trucks, 55 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.10 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. A. H0: p1=p2 H1: p1<p2 B. H0: p1<p2…
It has been determined that 37 out of 100 adult Americans that did not attend college believe in extra-terrestrials. However, from a random sample of 100 adult Americans that did not attend college 43 claim that they believe in extra-terrestrials. Does this indicate that the proportion of people who did not attend college and who believe in extra-terrestrials has changed? Conduct a hypothesis test with a = 0.01 and interpret the results.
The recommended dietary allowance (RDA) of vitamin C for women is 75 milligrams (mg) per day. A hypothesis test, with a significance level of 0.05, is to be performed to decide whether adult women are, on average, getting less than the RDA of 75 mg per day. A researcher gathers data from a random sample of women in order to carry out the test. Determine the Null and Alternative hypotheses.
