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 288 trials, the touch therapists were correct 127 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. Ho: p = 0.5 О В.

It was claimed recently that more than 55% of high school students in the United States use computers for educational purposes. We wish to examine this claim. We choose a random sample of 225 U.S. high school students and find that 140 of these students use computers for educational purposes. Based on this, can we conclude, at the 0.05 level of significance, that more than 55% of high school students in the United States use computers for educational purposes? In your answers, denote the proportion of all U.S. high school students who happen to use computers for educational purposes by p. State the null hypothesis H0 and the alternative hypothesis H1 Find the z-test value find the critical value Can we conclude that more than 55% of high school students in the United States use computers for educational purposes? Yes or No?
Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 5897 patients treated with this drug, 165 developed the adverse reaction of nausea.

Identify the null and alternative hypotheses, test statistics, P-value and state the final conclusion that addresses the original claim.
