Question
17. Concerning the data on impressio s of Hunter among Brooklyn and Queens residents, the decision on the Null hypothesis that the two proportions are the same at -0.10 is: a. Fail to reject the null hypothesis b. Reject the null hypothesis c. Inconclusive d. Partially fail to accept that the null hypothesis has been rejected. e. None of the above 18. Which of the following best describes what a P-value is? a. A P-value gives the probability of making a type Il error if the Null hypothesis is not rejected. A P-value gives the probability of making a type ll error if the Null hypothesis is rejected. A P-value gives the probability of making a type l error if the Null hypothesis is not rejected. A P-value gives the probability of making a type l error if the Null hypothesis is rejected. None of the above b. c. d. e. 19. Which of the following is most accurate? For a left-tailed test, we reject the Null hypothesis if: a. The level of significance is too high to comprehend. b. The test statistic is greater than some critical value, c. The test statistic is less than some negative critical value. d. The confidence level exceeds the significance level. e. None of the above.Explanation / Answer
17) need information about the data mentioned in the question to answer.
if P value is greater than 0.1 fail to reject null hypothesis
if P value is less than 0.1 reject null hyypothesis.
Use this to answer the question.
18) P value is the probability of making type I error when we reject null hypothesis.
option D is correct.
20) if left tailed test is used we reject null hypothesis when the observed value of test statistic is less than the critical value which is negative
for example the critical value for left tailed at alpha=0.1 is -1.645 .Reject null hypothesis if z<-1.645
from this it is clear that option C is correct. ( The test statistic is less than some negative critical value).
