The following data resulted from a taste test of two, Ask an Expert

Statistics

The following data resulted from a taste test of two different chocolate bars. The first number is a rating of the taste, which could range from 0 to 5, with a 5 indicating the person liked the taste. The second number indicates whether a "secret ingredient" was present. If the ingredient was present a code of "1" was used, and a "0" otherwise. At the .05 significance level, does this data show a difference in the taste ratings?
