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 293 trials, the touch therapists were correct 124 times. Use a 0.05 significance level to test the claim that touch therapists use a method equivalent to random guesses.

Can use of an online plagiarism-detection system reduce plagiarism in student research papers? The paper "Plagiarism and Technology: A Tool for Coping with Plagiarism"+ describes a study in which randomly selected research papers submitted by students during five semesters were analyzed for plagiarism. For each paper, the percentage of plagiarized words in the paper was determined by an online analysis. In each of the five semesters, students were told during the first two class meetings that they would have to submit an electronic version of their research papers and that the papers would be reviewed for plagiarism. Suppose that the number of papers sampled in each of the five semesters and the means and standard deviations for percentage of plagiarized words are as given in the accompanying table. Semester n Mean Standard deviation 1 2 3 4 5 36 43 34 6.32 3.34 1.77 34 1.82 33 1.50 3.75 3.08 3.25 3.12 2.39 For purposes of this exercise, assume that the conditions necessary for the…

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. 23) The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 lb. Assuming that CJ is known to be 121.2 lb, use a 0.10 significance level to test the claim that the population mean of all such employees weights is less than 200 lb. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Do one of the following, as appropriate: (a) Find the critical value Za/2- (b) find the critical value ta/2- (c) state that neither the normal nor the t distribution applies. 24) 99%; n = 17; CJ is unknown; population appears to be normally distributed.
