Hi can someone help me with that

Think about the context of the claim. Determine whether you want to support or reject the claim. a. State the null and alternative hypotheses in words. b. Write the null and alternative hypotheses in appropriate symbols (population parameters] c. Describe in words Type 1 error [the consequence of rejecting a true null hypothesis} [1. Describe in words Type 11 error [the consequence of failing to reject a false null hypothesis.) 1. You represent a chemical company that is being sued for paint damage to automobiles. You want to support the claim that the mean repair cost per automobile is more than $650. How would you write the null and alternative hypotheses? Ho in words: Ha in words: Ho: Ha: Type I Error: Type II Error: 2. You are on a research team that is investigating the mean temperature of adult humans. The commonly accepted claim is that the mean temperature is about 98.6F. You want to show that this claim is false. How would you write the null and alternative hypotheses? Ho in words: Ha in words: Ho: Ha: Type I Error: Type 11 Error: 3. As stated by a company's shipping department, the number of shipping errors per million shipments has a standard deviation that is less than 3. Can you support this claim? H0 in words: Ha in words: Ho: Type I Error: Ha: Type II Error: 4. A research organization reports that 33% of the residents in Ann Arbor, Michigan are college students. You want to reject this claim. Ho in words: Ha in words: Ho: Ha: Type I Error: Type II Error:5. In your work for a national health organization, you are asked to monitor the amount of sodium in a certain brand of cereal. You find that a random sample of 82 cereal servings has a mean sodium content of 233 milligrams. Assume the population standard deviation is 10 milligrams. At a = 0.01 , can you conclude that the mean sodium content per serving of cereal is different from 230 milligrams (a) (DESIGN) State your Hypotheses In words and (d) (DESIGN) Determine decision rule by determining parameters. the rejection region.(critical-value method) (e) (DATA) Conduct the test, mark the test statistics on the graph above, and circle your decision (b) (DESIGN) State Significance Level of the test and explain what Type I error is in context. Reject Ho Fall to Reject Ho (c) (DESIGN) Determine the statistical model (test statistic) (f) (CONCLUSION) State your overall conclusion in language that is clear, relates to the original problem and is consistent with your decision.A tourist agency in Florida claims the mean dally cost of meals and lodging for a family of four traveling in Florida Is no more than $284. You work for a consumer protection advocate and want to test this claim. In a random sample of 50 families of four traveling in Florida, the mean dally cost of meals and lodging is $292. Assume the population standard deviation is $25. At a = 0.05, do you have enough evidence to reject the agency's claim? (a) (DESIGN) State your Hypothesis (d) (DESIGN) Determine decision rule p-value method) (e) (DATA) Conduct the test, graph and shade the test statistic find the p-value and circle your decision. (b) (DESIGN) State Significance Level of the test and explain what Type II error would be. Reject Ho Fail to Reject Ho (c) (DESIGN) Determine the statistical model (test statistic] (f) (CONCLUSION) State your overall conclusion in language that is clear, relates to the original problem and is consistent with your decision
