An Italian restaurant is interested in comparing a new method
for preparing ravioli with the current method. They decide to
conduct a study, as described below, to determine which method they
will use. The study takes place over a two-week period and involves
all customers who order raviolis during that time. With each order,
a coin is flipped. If the coin lands on heads, the ravioli is
prepared using the new method; if the coin lands on tails, the
ravioli is prepared using the current method. After the meal, the
customers are given a short, anonymous questionnaire in which they
are asked to rate the quality of the ravioli on a scale of 1 to 10
(with larger numbers reflecting higher satisfaction). At the end of
two weeks the data are analyzed and the results compared. As
described in the example what is the response variable?
