In a survey, 31% 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 70 of them spoke to
their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the α = 0.05 level of significance.
Because np (1-P₁) = 51.3 > 10, the sample size is
satisfied.
(Round to one decimal place as needed.)
