In a survey, 44% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so she randomly selected 250 pet owners and discovered that 107 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a = 0.01 level of significance. Click here to view the standard normal distribution table (page 1), Click here to view the standard normal distribution table (page 2). Because npo (1- Po) =O > 10, the sample size is (Round to one decimal place as needed.) less than 5% of the population size, and the sample V the requirements for testing the hypothesis satisfied. are
