Problem 29

A high school counselor wonders if the type
of music played during lunch hour influences the speed with which students eat.
In one condition, soft, new-age music is piped through the sound system. In a
second condition, Hip Hop is played. Assume that relevant aspects of the
setting are controlled (e.g. menu, portions, seating arrangements, etc.). Six
students are observed for 5 minutes, and the dependent variable is the average
number of bites per minute. Since this is a repeated-measures design, half of
the participants listen to the New Age music first, and half of the
participants listen to Hip Hop first. The dependent variable is measured during
each experimental condition. Perform a Wilcoxon signed-ranks test on the
following data. Set alpha at .05.
