Timothy wants to estimate the percentage of homeowners that own at least one dog. He surveys 100 randomly selected homeowners to determine whether or not they own dogs. What is the parameter? all homeowners the percentage of surveyed homeowners that own at least one dog the 100 homeowners surveyed the percentage of all homeowners that own at least one dog specific responses to the survey

The parameter Timothy is interested in is the percentage of all homeowners that own at least one dog. This is the population parameter, which reflects the true proportion of dog owners in the entire population of homeowners, rather than just those surveyed. To make the survey more effective, Timothy could consider the geographical location of his sample. Homeownership rates and pet ownership can vary significantly between urban and rural areas, so ensuring a representative sample across different regions can help him get a more accurate estimate of dog ownership among all homeowners.
