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 Is there a significant difference between the two conditions? Use a two-tailed test with α = .01. n = df1 + df2 M1= M2= μ1-μ2 = SS1 + SS2= s2p = S(M1-M2) = Hypothesis: Locate critical region…

Work this problem involving a true/false and multiple choice test. Assume that the test has 7 true/false questions, and 11 muiltiple choice questions (3 options per questions), each with exactly one correct answer. If a student guesses randomly on each question, what is her expected score?
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…

Hi, could you help me with this question? Thank you!
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.
