A research company claims that no more than 55% of Americans regularly watch FOX News. You 10. decide to test this claim and ask a random sample of 425 Americans if they watch this network regularly. Of the 425 sampled, 255 respond yes. Calculate the test statistic for the hypothesis test.

Five years ago, a survey found that the proportion of cityemployees who commute to work by car is 8%. A local citycommissioner claims that the percentage is higher than it wasfive years ago. Data on employee commuting by car was collectedon a random sample of 1000 employees and found 12% of employeescommute by car.

hypothesis test. State your conclusion to the The mayor of a certain city is tasked with cutting over 5 million dollars out of next year's budget and is 13. considering cuts to spending on public transportation. The mayor decides to conduct a hypothesis test and will only cut spending on public transportation if fewer than 15% of residents use the service. In a random sample of 300 residents, 36 reported that they did use public transportation. Perform the appropriate hypothesis test at a 1% significance level. p value. 1. 4 (D evidence C-ovtd.ud.Q— a) Reject the null hypothesis.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
