- Question A physical therapist is interested in studying patients recovering from neck injuries. Let the proportion of neck injury patients who fully recover in less than 6 months be p. If the physical therapist wants to know if the proportion of neck injury patients who fully recover in less than 6 months is more than 75%, what are the null and alternative hypotheses? Select the correct answer below: H0: p=0.75; Ha: p>0.75 H0: p=0.75; Ha: p<0.75 H0: p>0.75; Ha: p=0.75 H0: μ=0.75; Ha: μ>0.75arrow_forwardAnswer the B questionarrow_forwardTest the claim that the average number of points scored in a college soccer game is no more than 5.5, if n = 70, x= 5.65, 0 = 1.37, and a is 0.05. Your response should include your decision and conclusion in context of the scenario.arrow_forward
- Heip Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A scientist claims that the mean incubation period for the eggs of a species of bird is more than 37 days. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim a statement of equality, it represents the hypothesis. (a) How should you interpret a decision that rejects the null hypothesis? There is evidence to the claim that the mean incubation period for the eggs of a species of bird is more than 37 days. (b) How should you interpret a decision that fails to reject the null hypothesis? There is evidence to the claim that the mean incubation period for the eggs of a species of bird is more than 37 days. Click to select your answer(s). Desktop , 见吗arrow_forward(1 point) Matt thinks that he has a special relationship with the number 2. In particular, Matt thinks that he would roll a 2 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Matt will roll a 2. (a) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for the population proportion, whichever symbols you need of "", "=", "not =" and express any values as a fraction e.g. p = 1/3) Ho = Ha = (b) Now suppose Matt makesn = 34 rolls, and a 2 comes up 7 times out of the 34 rolls. Determine the P-value of the test: P-value = (C) Answer the question: Does this sample provide evidence at the 5 percent level that Matt rolls a 2 more often than you'd expect? (Type: Yes or No)arrow_forwardHow do you find the signs and variables for a hypothesis?arrow_forward
- practe question #2. The average wait time for a ride at Disney World is 36 minutes. You are thinking about purchasing a Fastpass to see if it significantly shortens the wait time. You are debating because the Fastpass is expensive. a. What hypotheses should you use to test this claim about the Fastpass and wait times? (Set the hypotheses up with proper notation, but we will not perform a test) b. Explain what a Type I error and Type II error would be in this case (explain in context of the problem). Which one do you think is worse and why? We may be able to accept either answer based on your explanation.arrow_forwardExplain pleasearrow_forwardHow do you identify the chi sq & the p-value? How will you interpret the p-value?arrow_forward
