A veterinarian believed this result to be too high, so he randomly selected 220 pet owners and discovered that 63 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. Because npo (1 - Po) = 47.1 > 10, the sample size is less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied.

A sociologist tests whether this percentage is different today by conducting a random sample of 650 females aged 15 and older and finds that 382 are living alone. Is there sufficient evidence at the a = 0.05 level of significance to conclude the proportion has changed? Because npo (1 - Po ) = 158.3 > 10, the sample size is less than 5% of the population size, and the sample is a random sample, all of the requirements for testing the hypothesis are satisfied.
