- In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 350 trials, the touch therapists were correct 165 times. Complete parts (a) through (d).If the coefficient of determination between two independent variables is 0.33, what is the VIF? VIF= (Round to three decimal places as needed.)A physician wants to see if there was a difference in the average smokers' daily cigarette consumption after wearing a nicotine patch. The physician set up a study to track daily smoking consumption. In the study, the patients were given a placebo patch that did not contain nicotine for 4 weeks, then a nicotine patch for the following 4 weeks. Test to see if there was a difference in the average smoker's daily cigarette consumption using α = 0.01.

- The test statistic for testing HO: mu = 100 against Ha: mu != 100 wast 3.3, with p-value of 0.001. Which of these is the correct conclusion? Since the p-value is very small, we conclud that mu != 100 Since the p-vaue is very smal, we are unable to conlude that mu != 100 Since the p-value is very small, we must conclude the mu = 100 In order to interpret the results, we must first know the sample size. Since the p-value is very small, we are unable to conclude that mu = 100.We collected data for 300 people at a movie theater.
