In a survey, 43% 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 190 pet owners and discovered that 77 of them spoke to their pet on telephone. Does the veterinarian have a right to be skeptical? Use the a 0.1 level of significance. Because np (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 is given to be random, the requirements for testing the hypothesis are satisfied. What are the null and alternative hypotheses? Họ: 43 versus H,: H > 43 (Type integers or decimals. Do not round.) Find the test statistic, zo. z0 = (Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.) Does the veterinarian have a right to be skeptical? O A. The veterinarian does not have a right to be skeptical. There is not sufficient evidence to conclude that the true proportion of pet owners who talk to their pets on the telephone is 43%. O B. The veterinarian has a right to be skeptical. There is sufficient evidence to conclude that the true proportion of pet owners who talk to their pets on the telephone is less than 43%. The veterinarian does not have a right to be skentical. There is not sufficient evidence to conclude that the true nronortion of net owners who talk to thenir nets on the telephone is less than 43%
