A one-tailed sign test is applied to a set of paired data. There were 14 pairs and the 0.10 level of significance was selected. There were 9 pluses and 5 minuses. What is the decision regarding the null hypothesis? Fail to reject it Reject it Neither reject it nor fail to reject it based on information given None of the above
suppose the p value in a two tailed test is 0.0134 based on the same population sample and null hypothesis and assuming the test statistics z is negative what is the p value for a corresponding oat tailed test
A driving instructor is investigating whether the time a driver spends in a driver’s education course improves their score on the driver’s test. The instructor randomly selected 10 drivers from a driver’s education course and recorded the number of hours each driver attended the driver’s education course and their corresponding score on the driver’s test. Assuming all conditions for inference are met, which of the following significance tests should be used for the investigation? A. A chi-square test of independence B. A two-sample t-test for a difference between means C. A two-sample z-test for a difference between proportions D. A linear regression t-test for slope E. A matched pairs t-test for a mean difference
Which of the following statements about the False Discovery Rate (FDR) is correct? The FDR is the only method available for controlling multiple testing error in transcriptional profiling data The FDR cutoff value should be held to the same standard as the p-value cutoff when doing hypothesis testing The FDR can be interpreted as meaning “the proportion of the significant gene list one would expect to find significant by chance due to the multiple testing error” The FDR greatly simplifies analysis, allowing researchers to add many more treatment groups to their experimental designs Its best to save your signal intensity data before calculating the FDR, as the FDR calculation will change the signal values for all of your data

Among 243 trials, the touch therapists were correct 103 times. Use a 0.05 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective?

Several students were tested for reaction times (in thousandths of a second) using their right and left hands. (each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the subject.) REsults from five of the students are includedin the graph. Use a significance level to test the claim that there is no difference between the reaction times on the right and left hands.What are the hypothesis for this test?What is the test satistic?
