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. 10, the sample size is Because npo (1-Po) = (Round one decimal place as needed.) 5% of the population size, and the sample cannot be reasonably assumed to be random, the requirements for testing the hypothesis can be reasonably assumed to be random, is given to not be random, is given to be random, satisfied.

Follow-up Question
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-P) = 55.3 > 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: P = 0.36 versus H₁: р (Type integers or decimals. Do not round.) Find the test statistic, Zo. Zo = (Round to two decimal places as needed.) < 0.36 less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied.
