A psychologist is interested in whether hypnosis affects brain dominance. Twelve college students from the freshmen class are randomly sampled for an experiment.The experiment has two conditions which are given on different days.In condition 1, the students are hypnotized and then given a test that measures the relative dominance of the right and left hemispheres.The higher the score is, the higher the right hemisphere dominance.In condition 2, the same students are given the test again, only this time they are not hypnotized but are in their normal state of consciousness.The following scores are obtained:

a. What is the nondirectional alternative hypothesis?

b. What is the obtained probability using the sign test?

c. Using = 0.052tail, what is your conclusion?

d. What error could you be making by your conclusion in part "c"?

e. To what population does your conclusion apply?

f. How would your results change if = 0.012tail ?

sorry if this isn't where to post a question or how to do it, but I need help. I need to find someone who can solve these questions.
