Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data

(c) Are your estimates in parts (a) and (b) upper and lower estimates? Ex- plain. (A) (b) is a lower estimate and (a) is an upper estimate since v is a decreasing function of t. (B) (a) is a lower estimate and (b) is an upper estimate since v is an increasing function of t. (C) (a) and (b) are neither lower nor upper estimates since v is neither an increasing nor decreasing function of t. (d) Let's find an overestimate and underestimate of the distance traveled by the motorcycle during this time period.
