Suppose Jenny claims that she has the special ability to flip a coin so that the head comes up more than the tail. You don't believe her so you want to conduct an experiment testing her coin flipping ability. You asked her to flip a fair coin 20 times and you found that she got 15 heads out of 20 flips. If you conduct a directional sign test, which of the following code can help you compute the pp-value? A. pbinom(15, size = 20, prob = 0.5, lower.tail = F) B. binom.test(15, n = 20) C. pbinom(14, size = 20, prob = 0.5, lower.tail = F) D. A and B E. B and C

When people learn a new task, their performance usually improves when they are tested the next day, but only if they get 6 hours sleep (Sticckgold, et al., 2000). The following data demonstrate this phenomenon. The participants learned a visual discrimination task on one day. Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night. 6 hours sleep No sleep n =14 n = 14 M = 72 M = 65 SS = 932 SS = 706 Will the 6-hour sleep show a much higher performance rate? This time use a one-tail with alpha = .05 Show all of the steps. Remember use the attached t-distribution chart when obtaining your critical region.

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 331 trials, the touch therapists were correct 159 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? (Type an integer or decial. Do not round)

OSM HTAM MATH 1420 11. A roulette wheel has 38 slots around the rim. The first 36 slots are numbered from 1 to 36. Half of these 36 slots are red, and the other half are black. The remaining 2 slots are numbered 0 and 00 and are green. As the roulette wheel is spun in one direction, a small ivory ball is rolled along the rim in the opposite direction. The ball has an equally likely chance of falling into any one of the 38 slots. Find each of the following: a. The probability that the ball lands in a black slot. b. The probability that the ball lands on 0 or 00. C. The probability that the ball does not land on a number from 1 through 12 d. The probability that the ball lands on an odd number or on a green slot
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…

Among mammals, bears probably have the best sense of smell. You want to investigate this. You take food and place it in an airtight plastic container and randomly place it behind one of three panels. You repeat this 50 times. If the bear can correctly smell the food and press the panel with the food, he/she gets the food as a reward. You get the following results: Observed results Number of times the bear correctly presses the panel with food behind it: 43 Number of times the bear incorrectly presses one of the two panels without food behind it: 7 Can the bear smell the food? Give both the test statistic and the table value.
