A researcher conducts an experiment on human memory and recruits 15 people to participate in her study. She performs the 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?
Here the p-value is 0.17
considering significance level of 0.05, as p-value is greater than 0.05, fail to reject the null hypothesis.
There is not significant evidence to conclude that the treatment impacts human memory.
This suggests that her experimental treatment has no effect on memory.

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...
