Sample size, N = 3450
Point estimate of republican, p = 1789/3450 = 0.5186 = 51.86%
Z = 1.96 at 95% confidence level
Now,
True percentage of republican residing in California = p +/- Z*Sqrt [p91-p)/N] = 0.5186+/- 1.96* Sqrt [0.5186(1-0.5186)/3450] = 0.5186+/-0.017 = (0.5016,0.5356) = (50.16%,53.56%).
Theres not much work to show
art supplies price = p 60% = .60
just multiply p * .60 = price with sale
