9.11. Use Table D to find critical values for two-tailed tests for these values. a. a level of .01; df = 17 b. a level of .001; df = 46 c. a level of .05; df = 0o 9.16. Suppose a researcher chooses to use a = .01 rather than .05. What effect does this have on the probability of Type I and Type II errors? 4) Spatz 9.17 skip the last column (the p value part) 9.17. The following table has blanks for you to fill in. Look up critical values in Table D, decide if He should be rejected or retained, and give the probability figure that characterizes your confidence in that decision. Check the answer for each line when you complete it. (Be careful not to peek at the next answer.) I designed this table so that some common misconceptions will be revealed-just in case you acquired one. Two-Lailed or Critical Quest Reject M or P N level one-tailed test"? Value value retain A?

How close to the truth is the number that is registered? Suppose 12 cars traveled exactly 10 miles (measured by surveying) and the following mileage figures were recorded by the odometers. State the null hypothesis, choose an alternative hypothesis, perform a I test, and write a conclusion. 9.8 10.1 10.3 10.2 9.9 10.4 10.0 9.9 10.3 10.0 10.1 10.2
