Many hotel chains that offer free Wi-Fi service to their customers
have experienced increasing demand for Internet bandwidth and
increasing costs. Marriott International would like to test the

Wi - Fi devices exceeds 0.40. A random sample of 130 Marriott
customers found that 63 have two Wi - Fi devices. Marriott
International would like to set significance level of 0.05. What is
your conclusion?
