A political campaign is interested in whether a geographic difference existed in support for raising the minimum wage in a certain state. Polls were conducted in the two largest cities in the state about raising the minimum wage. In city 1, a poll of 800 randomly selected voters found that 548 supported raising the minimum wage. In city 2, a poll of 1000 randomly selected voters found that 641 supported raising the minimum wage. What type of hypothesis test should be performed? Select Pi = P2 = = Test statistic = p-value = Does sufficient evidence exist to support the claim that the level of support differs between the two cities at the a = 0.01 significance level?

What does it mean for the results of a hypothesis test to be statistically significant?
Compare statistical testing with legal methods used in a U.S. court setting. Then discuss the following topics in class or consider the topics on your own. Please write a brief but complete essay in which you answer the following questions. (a) In a court setting, the person charged with a crime is initially considered to be innocent. The claim of innocence is maintained until the jury returns with a decision. Explain how the claim of innocence could be taken to be the null hypothesis. Do we assume that the null hypothesis is true throughout the testing procedure?What would the alternate hypothesis be in a court setting?(b) The court claims that a person is innocent if the evidence against the person is not adequate to find him or her guilty. This does not mean, however, that the court has necessarily proved the person to be innocent. It simply means that the evidence against the person was not adequate for the jury to find him or her guilty. How does this situation compare with a…
A newsletter publisher believes that 48 % of their readers own a laptop. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.10 level of significance, the testing firm fails to reject the null hypothesis. What is the conclusion regarding the publisher’s claim?
If the null hypothesis is false, you cannot make which kind of error? Type I Type II
When performing a hypothesis test, what effect does increasing the sample size have on the probability of type I error?
If alpha is .10 in a two-tail hypothesis test, what is your decision rule for rejecting a null that the population mean is 200 if you use the Z test?
ANOVA is another kind of hypothesis testing. Did reading this section increase the understanding of hypothesis testing? How is an F-stat different from or similar to a z-score? Why are the hypothesis statements written differently for ANOVA than from the z-test?
Which of the following terms describes when the null hypothesis is NOT rejected when it should be rejected? O Significance level, a Type I error Type II error p-Value Alternative hypothesis
The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? Determine the test statistic. (Round ofd to 3 decimal places) Find the P-Value What is the conclusion? (In case you are using excel, I will appreciate if you explain the steps of finding the test statistic and the P-value....But this is not a must)
