According to a recent census, 17% of the people in the United States are of Hispanic origin. One county supervisor believes her county has a different proportion of Hispanic people than the nation as a whole. She looks at their most recent survey data, which was a random sample of 481 county residents, and found that 48 of those surveyed are of Hispanic origin. Complete parts (a) through (d) below.
