Previously, 12.1% of workers had a travel time to work of more than 60 minutes. An urban economist believes that the percentagehas increased since then. She randomly selects 80 workers and finds that 18 of them have a travel time to work that is more than 60minutes. Test the economist's belief at the x = 0.1 level of significance.What are the null and alternative hypotheses?P =0.121 versus H1: pHo: p(Type integers or decimals. Do not round.)>0.121Because npo (1- Po) =< 10, the normal model may not be used to approximate the P-value.(Round to one decimal place as needed.)

Given that Sample size n =80 Population proportion p=38%=12.1%=0.121

Test the claim that the proportion of men who own cats is significantly different than 15% at the 0.01 significance level. The null and alternative hypothesis would be: Ho:p 0.15 Ho:p= 0.15 Ho:u = Ho:u= Ho:= Ho:p 0.15 o H1:p> 0.15 H:p H:p# H: < H:p 0.15 |3D %3D O.
In November 2009 the average unemployment rate was 9.9% and in November 2019 a sample of 50 states showed it was 3.5%. At a .01 significance level can we conclude the employment rate has decreased? Show the six steps of hypothesis testing.
A publisher reports that 46% of their readers own a Jaguar. A marketing executive wants to test the claim that the percentage is actually more than the reported percentage. A random sample of 220 readers found that 50% of the readers owned a Jaguar. Is there sufficient evidence at the 0.05 level of significance to support the executive’s claim? H0: p = 0.46 Ha: p >> 0.46 Is this a one-tailed or a two-tailed test? Explain your reasoning.
Suppose 231 subjects are treated with a drug that is used to treat pain and 51 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. Ho: p=0.20 H₁: p>0.20 O B. Ho: p=0.20 H₁: p0.20 O C. Ho: p>0.20 H₁: p=0.20 D. Ho: p=0.20 H₁: p<0.20 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.)
In a study by von zur Muhlen et al. 136 subjects with syncope or near syncope were studied. Syncope is the temporary loss of consciousness due to sudden decline in blood flow to the brain. Of these subjects, 75 also reported having cardiovascular disease. The estimated proportion for the percent of people with this condition is 60%. a. Perform a test of hypothesis at an 80% confidence level. Use the p-value method and a two tailed test. b. Perform a test of hypothesis at a 90% confidence level. Use the critical value method and a left tailed test.
In general, if sample data are such that the null hypothesis is rejected at the ? = 1% level of significance based on a two-tailed test, is H0 also rejected at the ? = 1% level of significance for a corresponding one-tailed test? Explain your answer. Yes. If the two-tailed P-value is smaller than ?, the one-tailed area is also smaller than ?. No. If the two-tailed P-value is smaller than ?, the one-tailed area will be larger than ?. Yes. If the two-tailed P-value is smaller than ?, the one-tailed area will be larger than ?. No. If the two-tailed P-value is smaller than ?, the one-tailed area is also smaller than ?.
A hypothesis test was used to test the hypothesis that people with a significant other are happier on average than people without. The P-value was 0.07 and the level of significance used was 0.1. Then there is sufficient evidence to conclude that, on average, people with a significant other are happier than single people. True or False

Suppose that at a particular college, a random sample found that 25 out of 100 students who use the internet use Twitter. Does this provide evidence that the true proportion of students at this college who use Twitter is higher than the nationally stated 15%? Use a significance level of 0.05 and the p-value to give your decision. The correct hypotheses to use are: Ho: p = 0.15 HA: p > 0.15 Blank #1: Report the test statistic to two decimal places Blank #2: Report the p-value to four decimal places. Blank #3: Give the test decision: (reject or do not reject) Ho Blank #4: Evidence _[favors or does not favor) that the true proportion of students at this college who use Twitter is higher than the nationally stated 15%.
Internet tax: The Gallup Poll asked 1043 U.S. adults whether they believed that people should pay sales tax on items purchased over the internet. Of these, 407 said they supported such a tax. Does the survey provide convincing evidence that the percentage of U.S. adults who favor an internet sales tax differs from 40%? Use the a = 0.05 level of significance. Part 1 of 5 State the appropriate null and alternate hypotheses. Ho: p = 0.40 H:p = 0.40 This hypothesis test is a two-tailed test. Part: 1/5 Part 2 of 5 Find the critical values. Round the answers to at least three decimal places. For a = 0.05, the critical values are and
4. Following these overall patterns, what do you think the hypotheses would be to determine if a population proportion is different than 0.25? 5. Following these overall patterns, what do you think the hypotheses would be to determine whether a population variance is more than 337.4?
USA Today reported that about 47% of the general consumer population in the United States is loyal to the automobile manufacturer of their choice. Suppose Chevrolet did a study of a random sample of 1008 Chevrolet owners and found that 481 said they would buy another Chevrolet. Does this indicate that the population proportion of consumers loyal to Chevrolet is more than 47%? Use ? = 0.01. (a) What is the level of significance?State the null and alternate hypotheses. H0: p = 0.47; H1: p > 0.47H0: p = 0.47; H1: p < 0.47 H0: p > 0.47; H1: p = 0.47H0: p = 0.47; H1: p ≠ 0.47 (b) What sampling distribution will you use?
