Use the following scenario and data to answer questions12.1 – 12.5. A researcher is interested in how many daysit takes athletes to recover from jet lag when they have had to flya long distance. It is commonly known that traveling east (moving“ahead†in time) leads to more serious jet lag than travellingwest. The researcher finds 18 professional athletes who justtravelled a long distance; six stayed in the same time zone, sixtravelled west, and six travelled east.
Traveling West | Traveling East | Travel in Same Time Zone |

12.2 What is the value of N in thisexperiment?
12.3 What number should appear in thedenominator of your F-ratio? (I want the actual number,not the name of it)
12.4 What number should appear in the numeratorof your F-ratio? (I want the actual number, not the nameof it) (SHOW WORK)
12.5 Do the data show a significant differencein jet lag depending on the direction of travel? Use a two-tailedtest and alpha = .05.
