A survey was conducted in a large city to investigate public opinion on banning the use of trans fats in restaurant cooking. A random sample of 230 city residents with school age children was
selected, and another random sample of 341 city residents without school age children was also selected Of those with school age children 94 opposed the banning of trans fats, and of those
without school age children 147 opposed the banning of trans fats. An appropriate hypothesis test was conducted to investigate whether there was a difference between the two groups of
residents in their opposition to the banning of trans fats. Is there convincing statistical evidence of a difference between the two population proportions at the significance level of DAS?
