Test the B claim that the Mount Inn hotels are priced differently than the Pleasant Inn hotels, at the a = D 0.01 level of significance. I. ity Mount Inn Pleasant Inn Difference 90 96 96 102 98 100 1. What type of test should be used in this research? What should we do about the hypotheses? A. Accept the null hypothesis B. Reject the alternative hypothesis C. Reject the null hypothesis D. Cannot reject the null hypothesis. 6. A. One-sample t-test B. One-sample proportion z-test C. Two-sample Proportion z-test D. Two-independent sample z-test E. Two-independent sample t-test. At = 0.01, what is the research conclusion? 7. 2. Is it a one-tailed or two-tailed test? A. Left-tailed B. Right-tailed C. Two-tailed and right-tailed D. Two-tailed E. Two-tailed and left-tailed. A. There is insufficient evidence to conclude that the Pleasant Inn hotels are priced the same with the Mount Inn hotels B. There is insufficient evidence to conclude that the Mount Inn hotels are priced differently than the Pleasant Inn 3. What will be the research hypotheses? hotels C. There is sufficient evidence to conclude that the Pleasant Inn hotels are priced differently than the Mount Inn hotels D. There is sufficient evidence to conclude :M Inn-P Inn0 4. What is the critical value in the research? that the Mount Inn hotels are priced the A. 4.0321 B. 3.7074 C. 3.4995 D. 3.3554 E. 3.2498 same with the Pleasant Inn hotels. 8. Compute the upper boundary of the 93% C.I. for the estimated mean difference? A. 26.7510 B. 20.7829 C. 15.8700 D. 11.8260 E. 8.4970 5. What is the test statistic in the research? A. -0.6737 B. -0.8184 C. -0.9942 D. -1.2078 -1.4672Explanation / Answer
1. Two Dependent sample t -test. Option E may be correct.
2. Two tailed test
3. Option E is correct in hypothesis Test problem
4. Critical value is research
tcritical = t0.01, 6 = 3.7074
5. Average difference in prices dbar = -49 /7 = -7
Standard deviation of differnce sd = 18.628
Standard error of mean difference sed = sd / sqrt(n) = 18.628/ sqrt(7) = 7.0407
5. Test statistic
t = dbar /sed = (-7)/(7.0407) = - 0.9942
6. Cannot reject the null hypothesis. Option D is correct.
7. Option B is correct. There is insufficient evidence to conclude that Mount Inn Hotels are priced differently than Pleasant Inn hotels.
8. 93% upper boundry of mean difference = dbar +- tcritical * SE
= -7 + 2.2011 * 7.0407 = 8.4970
