(?) Locusts are grasshoppers that form dense swarms covering hundreds of square miles. A swarm of locusts will consume the leaves and stems of plants within its path, including, plants grown by farmers. For example, a swarm that formed in West Africa during 2003 caused a staggering 2.5 billion dollars of agricultural damage. The ability to predict a swarm can help people prepare for and respond to this emergency. For a swarm to occur, a population of locusts must grow very quickly within a single year. The growth of a population depends on the time required for each locust to develop from egg to adult. It locusts can develop in fewer than 40 days, the population will likely reach a size that triggers a swarm. The following linear model describes the relationship between temperature and development time of a locust: development time

(temperature) 132 d If the standard deviation of this model equals 4 days, what is the probability that a locust will develop in less than 40 days at a temperature of

? a. The probability is less than
