A 9-year-old girl did a science fair 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 sheasked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it.

let x: the touched therapists were correct . given information: x=112 n=274 α=0.1 claim: the touch therapist use a method equivalent to random guesses. hence null and alternative for the test is: D. H0:P=0.5H1:P≠ 0.5 Test statistics: z=p¯-pp¯*(1-p¯)n =0.408-0.50.408*(1-0.408)274 =-2.98533 p value for two sided alternative at 0.1 level of significance is - 0.00283273(by using standard normal probability distribution table) Result: if p value > level of significance then we accept null hypothesis otherwise reject it. from above result p value( 0.00283273,)< level of significance(0.1) hence we reject null hypothesis. D) reject H0. There is sufficient evidence to warrant rejection of the claim that touch therapist use the method equivalent to random guesses. conclusion: the touch therapist do not perform as random guesses . hence they do not equally effective.

A substance abuse counselor wants to demonstrate the effect of situational stress on alcohol cravings. He recruits two groups of men who are similar in respect to history of alcohol use and demographic variables. He divides them in to two groups. In one group(n=11), the men are exposed to a stressful situation and then asked to complete a measure rating their alcohol cravings on a scale from 0-10, where 0 representsno cravings and 10 represents intense cravings. In the second group (n=10), the men are exposed to a neutral situation and asked to complete the same measure. What test and graph should I create to find out if a stressful situation result in more intense alcohol cravings than a non-stressful situation?
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 340 trials, the touch therapists were correct 162 times. Complete parts (a) through (d). a. Given that Emily used a coin toss to select either her right hand or her left hand, what proportion of correct responses would be expected if the touch therapists made random guesses? 0.5 (Type an integer or a decimal. Do not round.) b. Using Emily's sample results, what is the best point estimate of the therapists' success rate? (Round to three decimal places as needed.)

Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
In PIMS hospital Islamabad there were patients who are in the early and middle stages of Alzheimer’s disease. Analyst have sought to examine the effect of various type of music on agitation levels in those patients. Patients were selected to participate in the study based on their stage of Alzheimer’s disease. Three forms of music were tested. Easy listening, Mozart and Piano interludes. While listening to music, agitation levels were recorded for the patients based on the heart rate in beats per minute. Test at 5% level of significance whether type’s music or early/middle stages of Alzheimer’s disease have significant effect on the agitation levels. Scores are recorded below: (6) Groups Piano interludes Mozart Easy listening Early stages of Alzheimer’s disease 103.5 104.7 100.2 105.9 Mean: 103.6 69.9 78.5 88.2 73.4 Mean: 77.5 95.6 99.3 101.4 120.1 Mean: 104.1 Middle stages of…
