What does a p-value from a hypothesis test not tell you?
 a. The direction of the difference or relationship (if one exists).
  b. How extreme the observed difference or relationship was.
  c. Whether or not your results are statistically significant.
  d. How likely it is to have observed these particular results (or more extreme ones) given that the null hypothesis is true.

Question 2

Journal articles very often report the p-value for their results, rather than just stating their conclusions as to whether or not they found a statistically significant result. Explain why this is important to you as an educated consumer of statistical information.

Answer to Question 1

A

Answer to Question 2

THE P-VALUE GIVES YOU AN IDEA OF THE STRENGTH OF THE DIFFERENCE OR THE RELATIONSHIP THAT WAS FOUND, AND YOU CAN USE IT TO MAKE YOUR OWN DECISION USING YOUR OWN SIGNIFICANCE LEVEL.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
