In a survey, 33% 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 210 pet owners and discovered that 66 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the α = 0.01 level of significance.

- Because \( n p_0 ( 1 - p_0 ) = \) [dropdown] ≥ 10, the sample size is [text box] ≥ 5% of the population size, and the sample [dropdown] the requirements for testing the hypothesis [dropdown] satisfied.
  (Round to one decimal place as needed.)

- What are the null and alternative hypotheses?
  \( H_0 : \) [text box] versus \( H_1 : \) [dropdown]

  (Type integers or decimals. Do not round.)

- Find the test statistic, \( z_0 \):
  \( z_0 = \) [text box] (Round to two decimal places as needed.)

- Find the P-value:
  P-value = [text box] (Round to three decimal places as needed.)

- Does the veterinarian have a right to be skeptical?

  - A. 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 33%.

  - B. 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 less than 33%.

  - C. 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 33%.

  - D. 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 not 33%.
