Select one answer A criminal investigator conducts a study on the accuracy of fingerprint matching and recruits a random sample of 35 people to participate. Since this 10 points is a random sample of people, we don't expect the fingerprints to match the comparison 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...

how could you rewrite or paraphrase this one: One possible limitation of this study is that the sample size is rather small for a university class. This may lead to the sample not being representative of the population because there are not many people in each experiment group. Another limitation of this study may be this study was conducted over one class during one semester. If the study was performed over multiple algebra classes at the college, the results may...
