Where the X's ('X-bar-one' and 'X-bar-two') are the means of the two independent samples (hence this is called an independent-samples t-test), the 's' represents the standard deviation for each group, and the N's each represent the respective sample sizes of each group.

Answer: Anchovies are a small, shiny, silver fish of the Anchoa (North America) or Engraulis (Mediterranean and European) family. Similar to herring, they run in large schools. Because they are small, generally 5 to 8 inches in length, anchovies are often confused with sardines (Sardinella anchovia). In some areas, the terms anchovy and sardine are used interchangeably. The minuscule scales are virtually non-existent and the skin is perfectly edible.
