A criminal investigator conducts a study on the accuracy of Select one answer. fingerprint matching and recruits a random sample of 35 people to 10 points participate. Since this is a random sample of people, we don't expect the fingerprints to match the compar omparison print. In the general population, a score of 80 indicates no match. Scores greater than 80 indicate a match. If the mean score suggests a match, then the fingerprint matching criteria are not accurate. The null hypothesis is that the mean match score is 80. The alternative hypothesis is that the mean match score is greater than 80. The criminal investigator chooses a 5% level of significance. She performs the experiment and analyzes the results. She uses a t-test for a mean and obtains a p-value of 0.04. Which of the following is a reasonable interpretation of her results? A. This suggests that there is evidence that the mean match score is greater than 80. This suggests that the fingerprint matching criteria are not accurate. B. If there is a treatment effect, the sample size was too small to detect it. This suggests that we need a larger sample to determine if the fingerprint matching criteria are not accurate. C. . She cannot reject the null hypothesis. This suggests that the fingerprint matching criteria could be accurate. D. . This suggests that there is evidence that the mean match score is equal to 80. This suggests that the fingerprint matching criteria is accurate. Question 8 A researcher conducts an experiment on human memory and Select one answer. recruits 15 people to participate in her study. She performs the 10 points experiment and analyzes the results. She uses a t-test for a mean and obtains a p-value of 0.17. Which of the following is a reasonable interpretation of her results? A. . This suggests that her experimental treatment has no effect on memory. B. . If there is a treatment effect, the sample size was too small to detect it. C. . She should reject the null hypothesis. D. . There is evidence of a small effect on memory by her experimental treatment
