The x-coordinate of an ordered pair is more than half the value of its corresponding y-coordinate. If the x-coordinate of the ordered pair is 10, what is the largest whole number value for the corresponding y-coordinate?

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.
