Lie Detector The table below includes results from polygraph (lie detector) experimentsconducted by researchers Charles R. Honts (Boise State University) and Gordon H. Barland(Department of Defense Polygraph Institute). In each case, it was known if the subject lied ordid not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significancelevel 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 truths and lies?NotificationsDid the Subject Actually Lie?No (Did Not Lie)Yes (Lied)Inbox

I need to turn this into a hypothesis test using a Ti84 As a dog owner I became curious as to the reason, why people choose to own a dog. I claim that more women choose to own a dog mainly for companionship than women who choose to have a large dog mainly for companionship. Do the data provide sufficient evidence to conclude that the proportion of women who prefer small dogs for companionship greater than the proportion of women who prefer large dogs for companionship? On Sunday, I will stand outside of my local Petco and survey women who are entering the store. I will ask if they own a dog, the main reason that they acquired a dog whether it was for protection or companionship and the size of their dog. I will collect this data in my notebook. I will not collect data from people exiting the store to ensure that I do not survey the same person more than once. I will acquire 30 samples of women who own small dogs and 30 women who own large dogs. I will not include women under the…

Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May , ). Hotel occupancy data for February in two consecutive years are as follows. Current Year Previous YearOccupied Rooms 1,470 1,360Total Rooms 1,750 1,700Conduct a hypothesis test. What is the -value (to decimals)? Use Table 1 from Appendix B. p-value = ?? Using a level of significance, what is your conclusion? d. What is the 95% confidence interval estimate of the change in occupancy for the one-year period (to decimal? to

The display provided from technology available below results from using data for a smartphone carrier's data speeds at airports to test the claim that they are from a population having a mean less than 5.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Click the icon to view the display from technology. .....
