Determine whether the statement is true or false. If it is false, rewrite it as a true statement. A large P-value in a test will favor a rejection of the null hypothesis. Choose the correct answer below. O A. True. OB. False. A large P-value in a test will favor a rejection of the alternative hypothesis. O C. False. A small P-value in a test will favor a rejection of the null hypothesis.

P-value =(Round to three decimal places as needed.)

S Identify the type I error and the type II error for a hypothesis test of the indicated claim. The percentage of adults who retire at age 65 is less than 62%. Identify the type I error. Choose the correct answer below. OA. Reject the null hypothesis that the percentage of adults who retire at age 65 is less than 62% when it is actually true. OB. Fail to reject the null hypothesis that the percentage of adults who retire at age 65 is greater than or equal to 62% when it is actually false. OC. Fail to reject the null hypothesis that the percentage of adults who retire at age 65 is less than 62% when it is actually false. OD. Reject the null hypothesis that the percentage of adults who retire at age 65 is greater than or equal to 62% when it is actually true.

Answer these question

Determine whether the statement is true or false. If it is false, rewrite it as a true statement. In a hypothesis test, you assume the alternative hypothesis is true. Choose the correct answer below. O A. True. O B. False. In a hypothesis test, you make no assumptions. OC. False. In a hypothesis test, you assume the null hypothesis is true.

Which of the following statements are TRUE? I. Increasing the significance level of a test will increase the chance of erroneously rejecting a true null hypothesis. II. Increasing the significance level of a test will increase the chance of erroneously failing to reject a false null hypothesis. Only statement I is true. Neither statement is true. Only statement II is true. Both statements are true.

Describe type I and type II errors for a hypothesis test of the indicated claim. A police station publicizes that at least 60% of applicants become police officers. Describe the type I error. Choose the correct answer below. O A. A type I error will occur when the actual proportion of applicants who become police officers is at most 0.60, but you reject Ho: p≤0.60. O B. A type I error will occur when the actual proportion of applicants who become police officers is at least 0.60, but you reject Ho: p20.60. OC. A type I error will occur when the actual proportion of applicants who become police officers is at most 0.60, but you fail to reject H₁: p≤0.60. OD. A type I error will occur when the actual proportion of applicants who become police officers is at least 0.60, but you fail to reject Ho: p² 0.60. Describe the type II error. Choose the correct answer below. O A. A type Il error will occur when the actual proportion of applicants who becomepolice officers is less than 0.60, but you…

You want to buy a washing machine, and a salesperson tells you that the mean repair costs for Model A and Model B are equal. You research the repair costs. The mean repair cost of 24 Model A washing machines is $212. Assume the population standard deviation is $17. The mean repair cost of 27 Model B washing machines is $230. Assume the population standard deviation is $24. At a = 0.01, can you reject the salesperson's claim? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e). ∞ (a) Identify the claim and state Ho and Ha What is the claim? O A. The mean repair costs for Model A and Model B are equal. OB. The mean repair cost for Model A is less than Model B. O C. The mean repair cost for Model A is greater than Model B. O D. The mean repair costs for Model A and Model B are different. Let μ, be the mean repair cost for Model A and let μ₂ be the mean repair cost for Model B. What are H, and H₂? oc Ho. Hi số Hz OB.…
