Davey, Startup, Zara, MacDonald, and Field (2003) were interested in the role of mood on the degree of compulsive checking in which a person engaged. (Compulsive checking is involved in a number of psychopathologies.) Three groups of 10 participants each listened to music designed to induce positive, negative, or neutral mood. They were then asked to "list as many things around your home that you should check for safety or security reasons before you go away for three weeks." The dependent variable was the number of things listed. The actual data follow.

5. Conclusions True or false: In hypothesis testing, it is never valid to form a conclusion of supporting the null hypothesis.
If a hypothesis test rejects the null hypothesis test at a = 0.05 will it also always reject the null at a = 0.01?
According to a New York Times/CBS News poll conducted during June 24–28, 2011, 55% of the American adults polled said that owning a home is a very important part of the American Dream (The New York Times, June 30, 2011). Suppose this result was true for the population of all American adults in 2011. In a recent poll of 1780 American adults, 60% said that owning a home is a very important part of the American Dream. Perform a hypothesis test to determine whether it is reasonable to conclude that the percentage of all American adults who currently hold this opinion is higher than 55%. Use a 10% significance level, and use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical value =Enter you answer; Critical value
If you are not able to prove the alternative hypothesis, this means the null hypothesis is correct. Select one: True False
Fomulate a Two independent means test hypothesis question.
When is a researcher at risk of making a type 2 error? whenever H0 is rejected whenever H1 is rejected whenever H0 fails to reject the risk of a type 2 is independent of the decision from a hypothesis test
Which is the alternative hypothesis?
Can you state the null hypothesis H0 and the alternative hypothesis H1? .
If a hypothesis test is performed and the null hypothesis is rejected in favor of the alternative hypothesis, does the test prove that the alternative hypothesis is correct? Choose the correct answer below. A.The test does not prove the alternative hypothesis correct, because only one test was done, and it takes at least hypothesis tests to prove a claim about a population parameter. B.The test does not prove the alternative hypothesis correct, because of the possibility of rejecting the null hypothesis when the null hypothesis is true. C.The test proves the alternative hypothesis correct, because once the null hypothesis is rejected, the only possibility that remains is for the alternative hypothesis to be true. D.The test proves the alternative hypothesis correct, because it shows that all the evidence suggests that the alternative hypothesis is true.
