4. Rosa reads an article in a magazine that says 37% of people talk to their pets on the answering machine or telephone. She can't believe that's true – her alternate hypothesis is that fewer than 37% of people talk to their pets that way. So Rosa conducts a survey of 150 random pet owners, and 51 of them say yes, they either talk to their pets on the phone or leave them a message on the answering machine. Test Rosa's hypothesis to a 10% level of significance.
