Changes in lifestyles over the years are believed to see families now eating more takeaway food at home for dinner than previously. It is claimed the proportion of families who now eat at least one takeaway meal per week as the family dinner is 75%. To test this claim, a random sample of 250 families is selected; 192 families indicate that they eat at least one takeaway meal per week as the family dinner. Using a 5% level of significance, what conclusion can be made? If the actual proportion of families who eat at least one takeaway meal per week as the family dinner is later found to be 83%, what error if any has been made?
