Cynthia works at a factory where they make chairs. At the beginning of the day as Cynthia greets other workers and gathers her materials, she gets little done. At the end of the day as she gets fatigued and as she cleans up her work station, her production drops off. The number of chairs Cynthia makes each hour can be modeled by the equation b = 6t - 0.75t^2 where b is the number of chairs and t is the number of hours since she begins her shift. Graph this situation on your calculator or on a sheet of paper. What is a reasonable domain and a reasonable range for this situation? A) D = 0 ? b ? 12, R = 0 ? t ? 8 B) D = 0 ? t ? 8, R = 0 ? b ? 12 C) D = b ? 12, R = t ? 8 D) D = t ? 8, R = b ? 12

An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 191 lb. The new population of pilots has normally distributed weights with a mean of 136 lb and a standard deviation of 30.3 lb. a. If a pilot is randomly selected, find the probability that his weight is between 130 lb and 191 lb. The probability is approximately (Round to four decimal places as needed) b. If 36 different pilots are randomly selected, find the probability that their mean weight is between 130 lb and 191 lb. The probability is approximately (Round to four decimal places as needed)
