Question

Consumption of fast food is a topic of interest to researchers in the field of nutrition. An article reported that 1880 of those in a random sample of 6765 U.S. children indicated that on a typical day, they ate fast food. Estimate p, the proportion of children in the United States who eat fast food on a typical day. (Round your answer to four decimal places.)

Answer 1

the proportion is 0.2779, that is a 27.79%

Explanation:

The article reported that 1880 children ate fast food from a sample of 6765 children. We can use the rule of three to find the proportion of children that ate fast food

• from 6765 we have 1880 children that ate fast food
• from 100 children we have
  `1880 * ((100)/(6765)) = 27.79` children that ate fast food

that gives us that a 27.79% of the children ate fast food on a typical day. We can obtain the proportion by dividing the percentage by 100, that gives us a proportion of 27.79/100 = 0.2779.
