- 9) In 2015, the average math SAT score for students at South Hanover High School was 520. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed since 2015. The hypotheses are: 12) A state fish hatchery raises trout for stocking streams and lakes. The size of the fish at release time can be controlled to a fair degree by varying the rate of feeding. The target is a mean of 10 ounces; if the fish are too small, those who catch the fish aren't happy. A random sample of 75 fish were weighed at time of release and it was determined that the mean was 9.66 ounces with a standard deviation of 0.86 ounces. Test to determine if the fish being released have a population mean less than 10 ounces at the 0.01 significance level. Ho : H = 520 Ha : µ # 520 Suppose that the results of the sampling lead to acceptance of the null hypothesis. Classify that conclusion as a Type I Error, a Type II Error, or a…A researcher is interested in examining whether doctors are as accurate at diagnosing certain illnesses via telehealth as they are in person. She randomly assigns a sample of doctors to either see patients via telehealth or in person, and assesses their diagnostic accuracy. What is the independent variable for the scenario A)The doctors B)Type of visit (telehealth vs in person) C)The patients D)Accuracy of diagnosis E)There is no IV for this type of analysisThe average life expectancy of tires produced by the Dunlop Tire Company has been 40,000 miles. Management believes that due to a new production process, the life expectancy of their tires has increased. In order to test the validity of their belief, the correct set of hypotheses is O a. Ho: H > 40,000 Ha:H S 40,000 O b. Ho:H 2 40,000 HaiH 40,000 O d. Ho: H <40,000 H3:H 2 40,000
- Let’s assume the average income for all majors in the School of Engineering is $80,000. However, the chair of the Computer Science department thinks their students earn more than that. Please choose the appropriate null and alternative hypotheses if the chair wanted to test this belief. a. H0: u <=80,000 Ha: u > 80,000 b. H0: u= 80000 Ha: u not= 80000 c. H0: u >80000 Ha: u < 80000 d. H0: u >80000 Ha: < 80000 e. None of the above.What are the class boundaries for the class limit, 2.20 - 3.80 ? 2.15 - 3.75 2.195 - 3.805 2.395 - 3.805 1.7 - 4.2For each of the following hypotheses, identify which statistical test we could run in order to address the specific research question being asked. Your options are: z-Test, One-Sample t-Test, Independent-Samples t-Test, and Paired-Samples t-Test. Be sure to mention a bit about the research design to explain why you chose that specific test: 1) Do the Dodgers and Giants differ in the number of strikeouts they have per game? 2) Does our stats class differ from the national average in IQ? 3) Do people perform better or worse on a cognitive task after they eat cookies? 4) Do "only children" drive safer than other children with siblings? 5) Do people have more friends in college than they did in high school? 6) Do people experience higher levels of sadness or anger after a specific negative outcome?
- You may need to use the appropriate appendix table or technology to answer this question. Carl Allen and Norm Nixon are two loan officers at a certain bank. The bank manager is interested in comparing the default rate on the loans approved by Carl to the default rate on the loans approved by Norm. In the sample of loans collected, there are 70 loans approved by Carl (21 of which defaulted) and 80 loans approved by Norm (17 of which defaulted). (a) State the hypothesis test that the default rates are the same for the two loan officers. (Let p1 = the population proportion of Carl's loans that default, and let p2 = the population proportion of Norm's loans that default. Enter != for ≠ as needed.) H0: Ha: (b) What is the sample default proportion for Carl? What is the sample default proportion for Norm? (c) Use a 0.05 level of significance. Calculate the test statistic. (Use p1 − p2. Round your answer to two decimal places.) What is the p-value? (Round…A group of veterinarians at a major veterinary hospital was interested in investigating a possible link between enteroliths, stones that form in the colon of horses, and diet. They decided to conduct a survey of feeding practices of horses in the hospital's state. They created a survey questionnaire and decided to administer it to the owners of every fifth horse being treated at the hospital. The population of interest is: A)all horses in the state. b) all horses that are diagnosed with enteroliths. C) None of the answer choices is correct. D)all horses brought to the clinic.In Blandford's PRETAR framework, the "R" (resources) includes (select all that apply): Group of answer choices funding environmental resources and green spaces availability of places to conduct the study equipment available for data collection and analysis
- a. If the new drug testing were to be placed in a test of hypothesis framework, would the null hypothesis be that the drug is safe or unsafe? The alternative hypothesis? b. Given the choice of null and alternative hypotheses in part a, describe Type I and Type II errors in terms of this application. Define a and ß in terms of this application. c. If the FDA wants to be very confident that the drug is safe before permitting it to be marketed, is it more important that a or ß be small? Explain.Choose from the choices and show the solution.A municipality’s local election board claims that 25% of registered voters typically cast ballots in annual school board elections. The local school board believes this percentage of participating voters is, in reality, much lower. What is the population parameter under consideration? What hypotheses should the local school board test in this situation?
