In a survey, 36% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so he randomly selected 240 pet owners and discovered that 85 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the α = 0.1 level of significance. Because npo (1-Po) = 10, the sample size is (Round to one decimal place as needed.) 5% of the population size, and the sample the requirements for testing the hypothesis satisfied.
