In a random sample of 800 U. S. adults in 2003, 398 considered the amount of federal income tax they had to pay to be too high. In a recent year, in a random sample of 1000 U. S. adults, 530 considered the amount too high. At α=.10 can you support the claim that the proportions of U. S. adults who considered the amount of federal income tax they had to pay to be too high was greater in 2003 than in the recent year?

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
