Question: Some people claim that werewolves come out on nights with a full moon. But what about vampires? The SPSS file Vampire_bites.sav contains actual data on the number of cattle bitten by vampire bats (vampire bates are a major livestock pest in Latin America) on nights with a new moon (no moonlight) and nights with a full moon.

Conduct a t-test to determine if vampire bites are more prevalent on full vs new moons. Report the t-value, degrees of freedom, v, and the significance level. Is there significant difference between the number of cattle bitten on nights with new and full moon? Which nights have the highest rates of bites - new or full?
