Question

Childhood obesity has more than tripled in the past 30 years. The percentage of children aged
     6–11 years in the United States who were obese increased from 7% in 1980 to nearly 20% in
     2008.   If this trend continues we can expect that the percent of young children that are obese
     in 2012 to be significantly greater than 20%. In order to test this claim, a random sample of
     800 children in the U.S. was taken and 179 of them were found to be obese. (Use a 5%
     significance level.)
