You have a rectangular piece of cardboard that is 6 feet long and 5 feet wide. You want to make a box, so you cut out squares of length x at each of the corners. You then fold the sides up to make a box with no top. If the volume of the box is 10 ft3, what was the size of the square you cut off of the corners?
Formulate an equation that you would use to solve for x, the edges of the squares.

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.
