Researchers investigated the effects of intercom music on the
likelihood of customers purchasing goods worth more than $200 on any
given day.  Retail outlets for a large electronics company were
randomly selected and put in two groups (those with and those without
music).  Of the 88 outlets where music was played, 44 experienced
average sales of $200 or more, while 21 of the 81 outlets in the
second group had sales of $200 or more.

Analyze the data collected from this study and propose a recommended
action for the electronics company.
