horizontal asymptote: y = –2, y = 2
vertical asymptote: x = 3
horizontal asymptote: y = –4, y = 1
vertical asymptote: x = 3
horizontal asymptote: y = 3
vertical asymptote: x = –4, x = 1
horizontal asymptote: y = 3
vertical asymptote: x = –2, x = 2

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
