PLEASE ONLY SELECT THE ANSWERS AS SHOWN FOR THE MULTIPLE CHOICE, SUCH AS OPTION 1, 2, ETC. 1) 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 she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. Among 297 trials, the touch therapists were correct 116 times. Use a 0.05 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. H0: p=0.5 H1: p>0.5 B. H0: p=0.5 H1: p≠0.5 C. H0: p≠0.5 H1: p=0.5 D. H0: p=0.5 H1: p<0.5 2) Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is…
How much more likely are alcoholics to say sober for a year after counseling if their best friend is not an alcoholic vs. if their best friend is an alcoholic? A researcher tracked 747 alcoholics whose best friends were not alcoholics and 517 alcoholics whose best friends were alcoholics. A year later 570 of those whose best friends were not alcoholics stayed sober for the year and 207 of those whose best friends were alcoholics stayed sober for the year. 1. Come up with the 99% confidence interval for the difference. Round your answers to four decimal places and present your answers as proportions rather than percents. ( __________ , ____________ )
A social and personality psychologist thinks that creativity differs by personality traits, rather than the traditional view that it is a cognitive process. Specifically, this psychologist thinks that introverts are more creative than extraverts. The researcher gives a personality test to a group of 16 university students and then separates them based on the assessment results into 2 groups: the extraverts and the introverts. The participants are then asked to write a short story which is rated on creativity by a well-known author. The creativity scores range from 0 to 20 on an interval scale, where higher scores indicate greater creativity. The results are shown in Table 2. Using the 0.05 alpha level, are introverts more creative than extroverts? Use all of the steps of hypothesis testing. extrovert introvert 8 18 7 17 11 10 3 14 5 16 8 15 7 19 4 12

A study on the relationship between watching TV as a child and violent acts as an adult, researchers followed the TV viewing habits of children between 1 and 10 years old. Of these kids, 85 watched less than 1 hour of TV per day, 350 watched between 13 hours, and 280 watched more than 3 hours per day. Ten years later, researchers evaluated the kids to determine if they had a criminal record. The number of aggressive acts by these children in these categories were 8, 84, and 68, respectively. Draw a contingency table with these observed results in the space below. Insert a similar table for the Expected results of HO: The amount of TV watching and violence are not associated. In reference to the TV watching question above, what is the value of your test statistic for this statistical test you would choose? For the TV watching data above, which of the choices below best matches your interpretation of the results for this statistical test? Group of answer choices a) The results were…
