3. Two methods of teaching statistics are being tried by a professor. A class of 40 students is taught by method A and a class of 36 is taught by method B. the two classes are given the same final examination. The scores are: X1= 78, X2 = 74. Using a 0.01 significance level, can we conclude that the average final examination scores produced by two methods are different if the population standard deviation is 5? %3D

Let’s take another look at the dinosaur example from the first part of the exam. Go ahead and figure out if smoking causes deaths in dinosaurs. Do not forget to follow all the steps of a hypothesis test; use =0.05, write out the conclusion. Smoking Die yes no TOTAL yes 1845 97 1942 no 496 1359 1855 TOTAL 2341 1456 3797
Use the six steps of hypothesis testing to answer the following question. Remember to determine if the problem is a Z test or T test as that will influence your critical value. You believe you have discovered a topical solution that heals wounds faster. The average number of days it takes to remove stiches after surgery in all hospital patients is 12. In a sample of 29 patients the average number of days to remove stiches is 10.5 with a std dev. Of 1.2 Did your solution lessen the number of days patients had stiches
STEPS IN STATISTICALHYPOTHESIS TESTING 1. Analyze the problem2. Formulate the null and alternative hypothesis3. Determine the tails of the test4. Determine the test to be used5. Compute6. Conclude Instruction:Using the steps in hypothesis testing, test the following hypotheses using the appropriate test statistic. A student would like to know which establishment would allow him to save more money from everyday food costs. He is choosing between AVM or Hollywood Terraces, so he traced his spending in both establishments for 1 school week each, his data is as follows:AVM: 97, 85, 69, 105, 105HT: 60, 45, 60, 75, 100

1. Define the critical region for a hypothesis test and explain how we use it to support or reject our null and alternative hypotheses. 2. Identify and explain the influence of the three factors that affect the value of the z-score in a hypothesis test. 3.Identify the steps of a hypothesis test and what additional measure should always be included. 4. Describe the difference between type I and type II error
For each scenario below read the given null and alternative hypotheses statements as well as the initial decision about the null hypothesis. Post a conclusion about the claim in each test. (This means when you post your answer, you do not need to include any statement about the null hypothesis. Only the final conclusion is needed.) **Chart 1 is attached** 1 Winning team data were collected for teams in different spots. use a .05 level of significance to test the claim that home/visitor wins are independent of the sport. **Table 1 is attached** P-Value=0.762
