A recent survey estimated that 19 percent of all people living in a certain region regularly use sunscreen when going outdoors. The margin of error for the estimate was 1 percentage point. Based on the estimate and the margin of error, which of the following is an appropriate conclusion? (A) Approximately 1% of all the people living in the region were surveyed. (B) Between 18% and 20% of all the people living in the region were surveyed. (C) All possible samples of the same size will result in between 18% and 20% of those surveyed indicating they regularly use sunscreen. (D) The probability is 0.01 that a person living in the region will use sunscreen when going outdoors. (F) It is plausible that the percent of all people living in the region who regularly use sunscreen is 18.5%.
