Question13: Hypothesis testing “Germany discovers love for plastic.”
Traditionally, cash has played a much larger role in Germany than in Canada. German attitudes are
slowly changing. A 2011 survey by the German central bank found that “only” 47% of Germans used
cash when paying a hotel bill. The survey was based on a sample of 2195 randomly selected Germans.
Test the hypothesis:
H0: 50% or less of Germans use cash to pay for hotel bills
H1: more than 50% of Germans pay cash for hotel bills.
What is the p-value ?
(Note: The barchart contains the percentage 47% butis otherwise not needed for this question).
